# 1.7362 (X12CrMo5) Open-Die Forgings: Rings, Flanges, Discs and Tubesheets **Source:** https://www.steelforgepieces.com/Alloy-Steel/1.7362.html **Manufacturer:** Jiangyin Jiangnan Metal Co., Ltd., open-die forging factory **Works:** No.1 Chengxiqiao Road, Zhouzhuang Town, Jiangyin City, Jiangsu Province, China **Contact:** sales@steelforgepieces.com | +86-189-2135-9659 **Last reviewed:** 7 September 2026 --- 1.7362 is the EN steel number for X11CrMo5 / X12CrMo5, a 5% chromium, 0.5% molybdenum creep-resistant alloy steel used for pressure-containing parts at high temperature. Jiangyin Jiangnan Metal Co., Ltd. forges it to customer drawing as seamless rolled rings, flanges, discs, tubesheets, sleeves, shafts, blocks and valve components, certified to ASTM A182 grade F5 or to the EN standard named on the order. **Also designated:** EN 1.7362, X11CrMo5, X12CrMo5, ASTM A182 F5, UNS K41545, 12CrMo19-5, ASTM A336 F5, ASTM A387 Gr.5, ASTM A335 P5, ASTM A213 T5, ASTM A234 WP5, ASTM A369 FP5, Type 501 / 502, GB 1Cr5Mo, GOST 15Kh5M, Z10CD5.05, JIS SFVA F5A, BS 625 **Key facts** | | | |---|---| | Nominal alloy content | 5% Cr, 0.5% Mo, creep-resistant grade | | Typical maximum continuous service temperature | 600 °C | | Minimum tensile strength, ASTM A182 F5 | 485 MPa | | Forged piece weight range | 20 kg to 20 t | --- ## What 1.7362 (X12CrMo5) is 1.7362 is a chromium-molybdenum alloy steel containing 4.00 to 6.00% chromium and 0.45 to 0.65% molybdenum. It retains useful strength at elevated temperature and resists oxidation, sulfidic corrosion and hydrogen attack under conditions where plain carbon steel is not suitable. Typical applications are refinery crude and vacuum units, hydrotreaters, catalytic reformers, coker heaters and the associated hot piping. The number 1.7362 is the EN material number. The steel name attached to it differs by standard, which is a frequent source of confusion on drawings: - **X11CrMo5** is the name used in EN 10216-2 for seamless pressure tubes, with delivery conditions `+I`, `+NT1` and `+NT2`. - **X12CrMo5** is the name used in EN 10028-2 for pressure-vessel plate and is widely used in trade. - **12CrMo19-5** is the older DIN designation, still found on legacy European drawings. All three carry the same material number, 1.7362, and the same nominal 5Cr-0.5Mo chemistry. For forgings, the specification normally applied is not the EN tube standard but **ASTM A182 grade F5** (flanges, forged fittings, valves and parts for high-temperature service) or **ASTM A336 grade F5** (forgings for pressure and high-temperature parts). The UNS number is K41545. **Why the grade is forged rather than cast or cut from plate.** Open-die forging closes ingot porosity, refines grain and aligns grain flow with the contour of the part. This produces more predictable through-thickness properties and fatigue behaviour than a cast or plate-fabricated equivalent. Pressure codes apply different rules to forgings and to plate fabrications for this reason. --- ## 1.7362 equivalent grades and standards Cross-reference for 1.7362 / X12CrMo5 (5Cr-0.5Mo), by standard and product form. | Standard | Designation | Product form | |---|---|---| | EN 10216-2 | X11CrMo5 (1.7362 +I / +NT1 / +NT2) | Seamless pressure tube | | EN 10028-2 | X12CrMo5 (1.7362) | Pressure-vessel plate | | Old DIN | 12CrMo19-5 | Legacy designation, all forms | | ASTM/ASME A182 | F5, UNS K41545 | **Forged flanges, fittings, valve parts** | | ASTM/ASME A336 | F5 | **Forgings for pressure and high-temperature parts** | | ASTM A387 | Grade 5 Class 1 / Class 2, UNS S50200 | Pressure-vessel plate | | ASTM A335 | P5 | Seamless ferritic alloy pipe | | ASTM A213 | T5 | Boiler, superheater and heat-exchanger tube | | ASTM A234 | WP5 | Wrought piping fittings | | ASTM A369 | FP5 | Forged and bored pipe | | ASTM A217 | C5 | Casting equivalent | | ASTM A193 / A194 | B5 / Grade 3 | Bolting and nuts | | AISI / UNS | Type 501 (S50100), Type 502 (S50200) | Bar and general | | GB/T (China) | 1Cr5Mo, 12Cr5Mo | All forms | | GOST (Russia) | 15Kh5M | All forms | | AFNOR (France) | Z10CD5.05 | All forms | | JIS (Japan) | SFVA F5A / F5B, STPA 25, STBA 25 | Forgings, pipe, tube | | BS (UK) | 625 | Legacy designation | | CSN | 17102 | Legacy designation | Cross-references are for guidance. Composition and mechanical limits differ in detail between these standards, and a forging can only be certified to the specification it was manufactured and tested to. One specification should be nominated on the purchase order. --- ## 1.7362 chemical composition 1.7362 contains 4.00 to 6.00% chromium and 0.45 to 0.65% molybdenum, with carbon limited to 0.15% maximum. Values are percentage by mass on the heat (ladle) analysis. Product analysis is permitted the tolerances given in the governing standard. | Element | EN 10216-2, X11CrMo5 (1.7362) | ASTM A182, grade F5 (K41545) | |---|---|---| | Carbon (C) | 0.08 to 0.15 | 0.15 max | | Silicon (Si) | 0.15 to 0.50 | 0.50 max | | Manganese (Mn) | 0.30 to 0.60 | 0.30 to 0.60 | | Phosphorus (P) | 0.025 max | 0.030 max | | Sulphur (S) | 0.020 max | 0.030 max | | Chromium (Cr) | 4.00 to 6.00 | 4.00 to 6.00 | | Molybdenum (Mo) | 0.45 to 0.65 | 0.44 to 0.65 | | Nickel (Ni) | 0.30 max | not specified | | Aluminium (Al, total) | 0.040 max | not specified | Elements not listed are not added deliberately without the purchaser's agreement. The full ladle analysis is reported, and a product analysis taken from the finished forging is available on request. --- ## 1.7362 mechanical properties For forgings to ASTM A182 grade F5, the required room-temperature minima are 485 MPa tensile strength, 275 MPa 0.2% proof strength, 20% elongation and 35% reduction of area, with hardness in the range 143 to 217 HBW. | Specification and condition | Rp0.2 min, MPa | Rm, MPa | A min, % | RA min, % | Hardness, HBW | |---|---|---|---|---|---| | ASTM A182 **F5**, annealed or normalised and tempered | 275 (40 ksi) | 485 min (70 ksi) | 20 | 35 | 143 to 217 | | ASTM A182 **F5a**, higher-carbon variant, K42544 | 450 (65 ksi) | 620 min (90 ksi) | 22 | 50 | 187 to 248 | | EN 10216-2 **1.7362+NT1**, wall thickness up to 100 mm | 280 | 480 to 640 | 20 | not specified | not specified | Elongation is measured on the standard proportional gauge length of the governing standard. EN delivery conditions `+I` and `+NT2` carry different values, available on request. **Note on published tensile values.** A number of 1.7362 datasheets quote 415 MPa tensile and 205 MPa yield. These are the ASTM A387 Grade 5 Class 1 plate values, not the forging values. Specifying A182 F5 or A336 F5 and then inspecting against 415/205 applies the wrong acceptance criteria. For reference, A387 Grade 5 Class 1 is 415 to 585 MPa tensile with 205 MPa minimum yield, and Class 2 is 515 to 690 MPa tensile with 310 MPa minimum yield. **Impact testing.** Charpy V-notch testing is not mandatory for A182 F5 at ambient temperature. It is routinely added by purchase order for pressure equipment and is required by several European codes. Testing can be carried out at room temperature or at a specified sub-zero temperature, on longitudinal or transverse specimens, with the three individual values and the average reported. --- ## Heat treatment and delivery condition 1.7362 forgings are supplied either annealed or normalised and tempered. ASTM A182 requires austenitising at 955 °C (1750 °F) minimum. Annealed parts are furnace cooled; normalised parts are air cooled and then tempered at 675 °C (1250 °F) minimum. | Route | Austenitise | Cool | Temper | Cool | |---|---|---|---|---| | A182 F5, annealed | 955 °C min | Furnace | not applicable | not applicable | | A182 F5, normalised and tempered | 955 °C min | Air | 675 °C min | Air | | EN 1.7362+NT1 | 930 to 980 °C | Air | 730 to 770 °C | Air | | EN 1.7362+NT2 | 930 to 980 °C | Air | 710 to 750 °C | Air | | EN 1.7362+I | Isothermal annealing, per EN 10216-2 | | | | Tempering temperature determines the final property balance. The lower `+NT2` temper gives higher strength; the higher `+NT1` temper gives better toughness and creep behaviour. Where design allowable stresses are derived from a particular delivery condition, the condition should be stated on the order in addition to the grade. Heat treatment is carried out in furnaces with calibrated multi-point thermocouples and continuous chart recording. The chart and the furnace calibration certificate are issued with the material test report. --- ## Physical properties and high-temperature behaviour 1.7362 is used for continuous service up to approximately 600 °C. ASME B16.5 pressure-temperature tables extend flange ratings for this material group to 649 °C. Density is approximately 7.75 g/cm³ and Young's modulus approximately 210 GPa at room temperature. The 5% chromium content provides four properties, in order of commercial significance: - **Sulfidic corrosion resistance.** In hot hydrocarbon streams containing sulphur compounds, common in crude and vacuum distillation, 5Cr steel corrodes considerably more slowly than carbon steel or 1.25Cr steel. This is the primary reason the grade is specified. - **Resistance to high-temperature hydrogen attack.** Chromium and molybdenum form stable carbides that resist decarburisation and fissuring by hydrogen under pressure, placing 5Cr-0.5Mo at a useful position on the Nelson curves used for hydroprocessing equipment. - **Creep strength.** Molybdenum maintains strength in the 450 to 600 °C range where carbon steel creeps. - **Oxidation resistance** in air and flue gas at elevated temperature. **Limitations.** 1.7362 is not a stainless steel. At 4 to 6% chromium it is below the approximately 10.5% required to form a passive film, so the material rusts in damp ambient conditions and requires preservation for storage and sea freight. It has no useful resistance to aqueous chloride or acid service. Where the duty is wet corrosion rather than high-temperature sulfidation, a stainless steel or nickel alloy is the correct selection. | Property at 20 °C | Typical value | |---|---| | Density | approx. 7.75 g/cm³ (7750 kg/m³) | | Young's modulus | approx. 210 GPa | | Structure after normalising and tempering | Tempered martensite or bainite with alloy carbides | | Magnetic | Ferromagnetic | | Weldability | Weldable with preheat and PWHT | --- ## 1.7362 forgings supplied Jiangyin Jiangnan Metal Co., Ltd. forges 1.7362 / X12CrMo5 into six product families, all to customer drawing, in the as-forged, rough-machined or finish-machined condition. **Rings and cylindrical parts.** Seamless rolled rings, retaining rings, sleeves, bushes and bushings, pipes and piping, tubes and tubings, barrels, casings, cases and shells, hollow bars, cylinders, hubs and housings. **Flanges and nozzles.** Weld-neck, blind, slip-on and long-weld-neck flanges, girth flanges, channel covers and cover flanges, self-reinforced FVC-type nozzles and nozzle necks, to ASME B16.5, ASME B16.47 Series A and B, EN 1092-1 or customer drawing. **Discs, tubesheets and tube plates.** Solid forged discs and disks, tubesheets, tube sheets and tube plates for shell-and-tube heat exchangers, front and rear, fixed, stationary and floating, including clad, cladded and weld-overlay (overlayed, coated) tubesheets where a corrosion-resistant face is required over the 1.7362 base. **Valve components.** Valve bodies and body blocks, bonnets, stems, closures, seat rings and other valve parts and components for hot service, Class 150 to Class 2500. **Shafts, bars and blocks.** Forged shafts, round bars, square and rectangular blocks, step shafts and stepped forgings. **Heat exchanger and pressure-vessel components.** Shell-and-tube heat exchanger components and parts, channel sections, girth flange sets, head forgings, and matched flange and tubesheet sets machined together. --- ## Size and weight range | Product | Outside diameter or size | Thickness or wall | Height or length | |---|---|---|---| | Seamless rolled rings | 200 to 3000 mm | 30 to 400 mm | up to 800 mm | | Discs and tubesheets | up to 3000 mm | 30 to 500 mm | not applicable | | Flanges | up to 3000 mm | up to 400 mm | not applicable | | Sleeves, hollow bars, cylinders | 150 to 2000 mm | 25 to 350 mm | up to 4000 mm | | Shafts and round bars | 80 to 1200 mm dia. | not applicable | up to 8000 mm | | Blocks and valve bodies | up to 1500 mm | up to 800 mm | up to 3000 mm | | Single-piece weight | 20 kg to 20000 kg | | | Forging equipment: hydraulic open-die presses to 2000 t and CNC radial-axial ring rolling mills. Parts outside these limits can often still be produced; send the drawing for confirmation. --- ## Manufacturing route for 1.7362 5Cr-0.5Mo steel is air-hardening. Uncontrolled cooling after forging produces martensite and retains hydrogen, which can cause delayed cracking. The route below is followed to prevent this. 1. **Melting and ingot supply.** Electric arc furnace with ladle refining and vacuum degassing as standard, and electroslag remelting where the specification or section size requires it. Each heat arrives with its own certificate and is segregated by heat number. 2. **Incoming inspection.** Chemistry verified on an in-house spectrometer against the mill certificate before the ingot is cut. 3. **Heating.** Soaked to 1180 to 1220 °C on a controlled ramp, with soak time set by section thickness. 4. **Open-die forging or ring rolling.** Upsetting and drawing on the press, or piercing and radial-axial rolling for rings, with a minimum forging reduction ratio of 3:1 and finishing temperature held above 900 °C so that the final deformation recrystallises the grain. 5. **Post-forge slow cooling and dehydrogenation.** Transferred directly from the press to a furnace for controlled cooling and a dehydrogenation hold. Omitting this hold is a common cause of delayed cracking in 5Cr forgings. 6. **Heat treatment.** Annealing, or normalising and tempering, to the condition stated on the order, in a calibrated furnace with multi-point thermocouples and continuous chart recording. 7. **Rough machining.** Proof machining to expose the surface for inspection, with test prolongations left attached where the specification requires integral test material. 8. **Testing and NDT.** Chemistry, mechanical testing and non-destructive examination. 9. **Finish machining, marking and preservation.** Final machining to drawing, hard stamping or vibro-etching of heat number, grade, specification and purchase order number, rust-preventive coating, and packing in fumigated cases for sea freight. --- ## Testing, inspection and certification Each 1.7362 forging is dispatched with an EN 10204 3.1 material test report covering chemistry, heat treatment, mechanical results, non-destructive testing and dimensions. EN 10204 3.2 reports countersigned by a third-party body are available to order. | Test | Method | Scope | |---|---|---| | Chemical analysis | Optical emission spectrometry | Ladle analysis standard; product analysis on request | | Tensile | ASTM A370 / ISO 6892-1 | Standard, per heat and heat-treatment lot | | Hardness | Brinell, ASTM E10 | Standard | | Charpy V-notch impact | ASTM A370 / ISO 148-1 | On request, ambient or low temperature | | Ultrasonic testing | ASTM A388 / EN 10228-3 | Standard on rings, discs and tubesheets | | Magnetic particle testing | ASTM E709 / EN 10228-1 | Standard on machined surfaces | | Liquid penetrant testing | ASTM E165 | On request | | Grain size and microstructure | ASTM E112 | On request | | Dimensional | To customer drawing | Standard, report issued | | Positive material identification | Portable XRF | On request, before dispatch | Quality system and approvals: ISO 9001 certified. Forgings are supplied under PED 2014/68/EU with AD 2000-Merkblatt W0 material appraisal. Third-party inspection is regularly witnessed by TUV, SGS, BV, Lloyd's Register and DNV. --- ## Applications for 1.7362 forgings - **Oil refining.** Crude and vacuum distillation, hydrotreating, hydrocracking, catalytic reforming and delayed coking, where hot hydrocarbon contains sulphur. - **Petrochemical plant.** Reactor internals and nozzles, transfer-line components, hot separator parts. - **Power generation.** Boiler headers, superheater and reheater components, main and auxiliary steam line fittings. - **Heat exchangers and pressure vessels** operating in the creep range, including clad and weld-overlay tubesheets. - **Valves and flanges** for hot service, Class 150 to Class 2500, to ASME B16.5 and B16.47. - **Fired heaters.** Return bends, headers and support components in convection and radiant sections. --- ## Welding and machining 1.7362 **Welding.** 1.7362 requires preheat, matching 5Cr consumables and post-weld heat treatment. Typical practice is preheat and interpass temperature of 200 to 300 °C, AWS E502 or ER502 (B6 group) consumables, and PWHT at approximately 700 to 760 °C with controlled cooling. Actual values are set by the applicable code and the qualified welding procedure. Preheat should be maintained continuously until PWHT begins rather than allowing the joint to cool between passes. Consumables should be low-hydrogen, baked and held in heated quivers. Arc strikes on the parent material produce untempered martensite that a visual inspection will not detect, and should be avoided. **Machining.** Machinability is good in the annealed condition and moderate after normalising and tempering. Carbide tooling, rigid setups, positive rake and generous coolant are the usual requirements. The steel work-hardens less than austenitic stainless, so feed rates can be maintained; heat generation is the limiting factor. For close tolerances on large rings or tubesheets, the normal sequence is rough machining, stress relief, then finish machining, so that residual stress does not move the part after dispatch. **Storage.** Because the grade is not stainless, 1.7362 requires rust preventive from the point of final machining. Forgings are shipped with a preservative film and vapour-phase inhibitor in sealed packing, and should be kept dry on site. --- ## How to order 1.7362 forgings Supply the following and a firm quotation normally follows within 24 hours. 1. **Drawing or sketch** with dimensions and machining allowance, or the raw forging envelope if machining is carried out in house. 2. **Specification and grade**, for example ASTM A182 F5 or EN 1.7362+NT1.

It is standardised in EN 10216-2, EN 10028-2 and EN 10222, and is the European equivalent of ASTM A182 grade F5 (UNS K41545). It is used for pressure-containing parts operating at elevated temperature, mainly in refineries, boilers and petrochemical plant. **Is 1.7362 the same as ASTM A182 F5?** They are the standard cross-reference for one another but are not identical specifications. Both are 5Cr-0.5Mo steels with 4.00 to 6.00% Cr and 0.45 to 0.65% Mo. A182 F5 is the American forging specification; 1.7362 / X11CrMo5 is the European grade. Carbon, silicon, phosphorus and sulphur limits differ, so a forging should be manufactured and certified to one nominated specification. **What is the difference between A182 F5 and F5a?** Carbon content and strength. F5 (K41545) permits 0.15% carbon maximum and requires 485 MPa tensile and 275 MPa yield minimum. F5a (K42544) permits 0.25% carbon maximum and requires 620 MPa tensile and 450 MPa yield minimum. Before 1995 the higher-carbon grade was designated F5, so drawings predating that change should be clarified before ordering. **What are the mechanical properties of 1.7362 forgings?** To ASTM A182 F5, annealed or normalised and tempered: tensile 485 MPa minimum, 0.2% proof strength 275 MPa minimum, elongation 20% minimum, reduction of area 35% minimum, hardness 143 to 217 HBW. To EN 10216-2 in the +NT1 condition: proof strength 280 MPa minimum, tensile 480 to 640 MPa, elongation 20% minimum. **Is 1.7362 a stainless steel?** No. At 4 to 6% chromium it is below the approximately 10.5% required to form a passive film, so 1.7362 is a low-alloy creep-resistant steel rather than a stainless steel. It rusts in damp ambient conditions and requires preservation in storage and transit. The chromium provides high-temperature strength and resistance to sulfidic corrosion and hydrogen attack rather than wet corrosion resistance. **What is the maximum service temperature of 1.7362?** It is normally used for continuous service up to approximately 600 °C, and ASME B16.5 pressure-temperature tables extend flange ratings for this material group to 649 °C. The limit for a given item depends on the design code, pressure, hydrogen partial pressure and design life, so the applicable allowable stress tables govern. **Does 1.7362 need preheat and post-weld heat treatment?** Yes. The steel is air-hardening, and welding without thermal control leaves hard, crack-sensitive martensite in the heat-affected zone. Normal practice is preheat and interpass temperature of 200 to 300 °C, matching 5Cr consumables such as AWS E502 or ER502, and PWHT at approximately 700 to 760 °C with controlled cooling. The applicable code and the qualified welding procedure set the actual values. **Which forged products can be made in 1.7362?** Jiangyin Jiangnan Metal Co., Ltd. supplies 1.7362 as seamless rolled rings; weld-neck, blind, girth, cover and long-weld-neck flanges; self-reinforced FVC nozzles; discs, tubesheets and tube plates including weld-overlay clad; sleeves, bushes, hollow bars, cylinders, barrels, casings and shells; shafts, round bars, blocks, hubs and housings; and valve bodies, bonnets, stems, closures and seat rings. **What certificates come with the forgings?** An EN 10204 3.1 material test report as standard, covering heat number, ladle and product analysis, heat-treatment record and chart, mechanical results and NDT reports. EN 10204 3.2 countersigned by a third-party body such as TUV, SGS, BV, Lloyd's Register or DNV is available where the purchase order requires it. **Who manufactures 1.7362 open-die forgings in China?** Jiangyin Jiangnan Metal Co., Ltd. is an open-die forging factory at No.1 Chengxiqiao Road, Zhouzhuang Town, Jiangyin City, Jiangsu Province, China, producing 1.7362 / X12CrMo5 (ASTM A182 F5) rings, flanges, tubesheets, shafts and valve components to customer drawing.
