NiMo28 Forgings
Seamless rolled rings, flanges, round bars, discs, shafts, sleeves, bushings and tube sheets, open-die forged in nickel-molybdenum alloy NiMo28 to DIN 17744 and ASTM B564 / ASME SB-564.
NiMo28 (W.Nr. 2.4617, UNS N10665) is a wrought nickel-molybdenum alloy containing 27 to 29% molybdenum with nickel as the balance. Chromium is capped at 1% and iron at 2%, so the alloy does not rely on a passive oxide film for its corrosion resistance. It is used for hydrochloric acid at all concentrations up to the boiling point and for other reducing acids, and it is not suitable for oxidising media. NiMo28 is a solid-solution alloy and is not age-hardenable.
Jiangyin Jiangnan Metal Co., Ltd. is an open-die forging factory at No.1 Chengxiqiao Road, Zhouzhuang Town, Jiangyin City, Jiangsu Province, China. It forges NiMo28 to customer drawings: rings, flanges, bars, discs, shafts, sleeves, bushings and tube sheets. Parts are supplied solution annealed and rapidly quenched, ultrasonically tested and certified to EN 10204 3.1 or 3.2. For a quotation, contact sales@steelforgepieces.com or +86 189 2135 9659.

What NiMo28 is, and when to specify it
Corrosion resistance in NiMo28 comes from the nickel-molybdenum matrix itself rather than from a passive chromium-oxide film. Chromium is limited to 1% and iron to 2%. Because there is no protective film to break down, the alloy holds up in hot, concentrated, de-aerated hydrochloric acid where stainless steels and nickel-chromium-molybdenum grades do not.
The same chemistry sets the limit. With no chromium available to rebuild an oxide layer, NiMo28 is attacked quickly by oxidising species: nitric acid, ferric or cupric salts, wet chlorine, or dissolved oxygen carried in with the feed. When specifying the grade, the controlling question is not acid concentration but whether oxidising species are present in the stream.
NiMo28 is the original member of the B family and has a known limitation. Held around 600 to 800 °C it forms an ordered Ni4Mo (beta) phase that reduces ductility and can leave a weld heat-affected zone open to attack. Alloy B-3 was developed to suppress that reaction. For fully annealed, static, correctly quenched equipment held outside that temperature band, NiMo28 remains suitable and costs less, and it is the designation most European specifications call up by name.
State UNS N10665 plus the product standard on the purchase order; for forgings that is ASTM B564. The DIN name NiMo28 and the Werkstoff number 2.4617 identify the same material, but the UNS number with a product standard is the least ambiguous form and is what the mill certificate carries.
Chemical composition of NiMo28 (UNS N10665)
The table below is the specification range Jiangyin Jiangnan Metal forges to. Every heat is supplied with a ladle analysis on the mill certificate, and product analysis on the finished forging can be added on request. The two highlighted rows are the composition controls that govern corrosion performance.
| Element | Minimum % | Maximum % | Role in the alloy |
|---|---|---|---|
| Molybdenum (Mo) | 27.0 | 29.0 | The active element. Provides resistance to hydrochloric and other reducing acids |
| Nickel (Ni) | Balance (approx. 66 to 70) | Base element. Supplies the nobility the alloy relies on in place of a passive film | |
| Iron (Fe) | — | 2.0 | Held low. Iron reduces resistance in hot concentrated HCl |
| Chromium (Cr) | — | 1.0 | Residual only. The alloy is not designed to passivate |
| Cobalt (Co) | — | 1.0 | Residual limit, also controlled for nuclear service |
| Manganese (Mn) | — | 1.0 | Deoxidiser, combines with sulfur |
| Silicon (Si) | — | 0.10 | Kept low. High silicon promotes embrittling phases |
| Carbon (C) | — | 0.02 | Low carbon limits grain-boundary carbide precipitation during welding |
| Phosphorus (P) | — | 0.04 | Residual limit |
| Sulfur (S) | — | 0.03 | Kept low for hot workability |

Mechanical properties of NiMo28 forgings
Typical room-temperature values, solution annealed
These are representative results for solution-annealed and rapidly quenched NiMo28 forgings. They vary with section size and quench rate, and a heavy section cooling more slowly at the core will normally test at the lower end.
| Property | Metric | Imperial |
|---|---|---|
| Tensile strength, Rm | 917 MPa | 133,000 psi |
| Yield strength, Rp0.2 | 396 MPa | 57,400 psi |
| Elongation at break, in 50.8 mm (2 in) | 55 % | 55 % |
| Hardness, Rockwell B | 98 HRB | 98 HRB |
| Hardness, Vickers (converted) | 241 HV | 241 HV |
| Hardness, Brinell (converted) | 168 HB | 168 HB |
| Hardness, Knoop (converted) | 186 HK | 186 HK |
Hardness values converted from Rockwell B. Typical values are for design screening. The mill test certificate issued with each forging governs acceptance. Acceptance minima are those of the product standard in force (ASTM B564 / B335 or DIN 17744) or of the purchase specification, whichever is stricter. State them on the order and they will be certified.
Physical properties
| Property | Metric | Imperial |
|---|---|---|
| Density | 9.22 g/cm³ | 0.333 lb/in³ |
| Melting range | ≈1,330 to 1,380 °C | ≈2,425 to 2,515 °F |
| Modulus of elasticity | ≈217 GPa | ≈31.5 × 10⁶ psi |
| Thermal conductivity, 20 °C | ≈11.1 W/m·K | ≈77 Btu·in/ft²·h·°F |
| Mean expansion, 20 to 100 °C | ≈10.3 µm/m·K | ≈5.7 × 10⁻⁶ in/in·°F |
| Specific heat | ≈373 J/kg·K | ≈0.089 Btu/lb·°F |
| Electrical resistivity | ≈1.37 µΩ·m | ≈824 Ω·circ mil/ft |
| Magnetic response | Essentially non-magnetic in the annealed condition | |
Nominal values compiled from published alloy literature for guidance. Thermal expansion is around 10.3 µm/m·K, below that of austenitic stainless steel, which matters where NiMo28 parts are bolted or welded to a stainless structure.
Corrosion behaviour of NiMo28
NiMo28 performs well in reducing conditions and poorly in oxidising conditions. The dividing line is oxidising potential, not acid concentration.
| Resists well | Do not use in |
|---|---|
| Hydrochloric acid, all concentrations, ambient to boiling | Nitric acid and other oxidising acids, at any strength |
| Sulfuric acid over a wide concentration range | Ferric chloride (Fe³⁺) and cupric chloride (Cu²⁺) solutions |
| Phosphoric, acetic and formic acids | Wet chlorine, hypochlorite and other oxidising bleaches |
| Hydrogen chloride gas, dry and moist | Aerated or oxygenated acid streams |
| Non-oxidising chloride salts, aluminium chloride catalyst systems | Mixed acids where the redox potential can move oxidising |
A few parts per million of ferric or cupric ions in hydrochloric acid, picked up from upstream carbon-steel pipework, a leaking cooler or air ingress, will raise the corrosion rate of NiMo28 by orders of magnitude. Where the stream cannot be kept reducing and clean, specify a nickel-chromium-molybdenum grade such as Alloy C-276, Alloy C-22 or Alloy 59, which tolerate both reducing and oxidising conditions.
Do not hold NiMo28 in the range 600 to 800 °C. Ordered Ni4Mo (beta) phase forms, ductility drops, and the weld heat-affected zone becomes open to preferential attack. This applies to service exposure, to slow cooling after annealing, and to welding heat input. Where thermal cycling is unavoidable, specify Alloy B-3 instead, which is stabilised against the same reaction.
NiMo28, Alloy B-3 and Alloy B-4 compared
All three are nickel-molybdenum alloys with roughly 28% Mo and comparable resistance to hydrochloric acid. They differ in thermal stability, which governs how well they survive welding, thermal cycling and time spent in the intermediate temperature band.
| Criterion | NiMo28 / Alloy B-2 | Alloy B-3 | Alloy B-4 |
|---|---|---|---|
| UNS number | N10665 | N10675 | N10629 |
| DIN / Werkstoff | 2.4617 · NiMo28 | Confirm the Werkstoff number against the mill certificate | |
| Nominal Mo | ≈28% | ≈28.5% | ≈28% |
| Thermal stability | Beta phase ordering at 600 to 800 °C | Stabilised, markedly better | Stabilised, better than B-2 |
| Weld HAZ behaviour | Open to attack, post-weld anneal advised for severe duty | Tolerant of welding | Tolerant of welding |
| HCl resistance | Excellent | Excellent | Excellent |
| Oxidising media | Unsuitable. The whole B family shares this limit | ||
| Relative cost | Lowest of the three | Highest | Between the two |
| Select it when | Fully annealed static equipment, no thermal cycling, cost matters, or the specification names 2.4617 | Welded fabrications, thermal cycling, or HAZ attack has occurred before | European projects specifying the stabilised grade |
Where the drawing states 2.4617 or NiMo28 and the part is a solution-annealed forging that will not be welded into a thermally cycled assembly, NiMo28 is correct and is the economical choice. Where it will be welded and cycled, include Alloy B-3 on the enquiry and compare. Jiangyin Jiangnan Metal forges all three.

Machining allowance is normally 6 to 20 mm per surface depending on section size, unless the drawing states otherwise. Finish-machined parts to print are also supplied. For nickel-molybdenum alloys the practical maximum is set by available ingot size rather than by press capacity, so confirm large sizes with the enquiry. Plant: 1 t, 3 t, 5 t and 9 t open-die hammers, a 5,000-tonne hydraulic press, and 3 m and 6 m seamless ring-rolling mills.
How we make NiMo28 forgings
- Melting. NiMo28 stock is melted by EAF and VOD, with ESR remelting to improve cleanliness and reduce segregation. Low silicon and low carbon are controlled at this stage rather than corrected later.
- Heat verification. Heat chemistry is checked by optical emission spectrometer against the NiMo28 limits, with particular attention to iron and carbon, before any material is heated.
- Open-die forging. Hot worked from approximately 1,175 °C down to 900 °C with a controlled reduction ratio, to close porosity and develop a wrought grain flow that follows the part contour. Rings are ring-rolled seamless. The workpiece is reheated rather than finished below the minimum forging temperature.
- Solution annealing. Held at approximately 1,065 °C (1,950 °F), then rapid water quenched. NiMo28 is not age hardened. The quench rate through 800 to 600 °C prevents beta phase ordering, so heavy sections are quenched rapidly.
- Descaling and machining. Descaled and pickled, then rough or finish machined to drawing with the agreed allowance. NiMo28 work-hardens quickly, so rigid setups, positive rake tooling, modest speeds, heavy positive feeds and flood coolant are used.
- Non-destructive testing. Ultrasonic examination to EN 10228-3, SEP 1921, ASTM A388 or a nominated class. Liquid penetrant and dimensional inspection as required.
- Certification and despatch. EN 10204 3.1 mill certificate as standard, 3.2 with third-party witness (TÜV, BV, LR, SGS, DNV) on request. Hard stamped, preserved and packed for sea or air freight.

Frequently asked questions about NiMo28
What is NiMo28?
NiMo28 is the German (DIN 17744) name for a wrought nickel-molybdenum alloy carrying Werkstoff number 2.4617 and UNS number N10665. It contains 27 to 29% molybdenum with nickel as the balance, and low chromium (1% max) and iron (2% max). It is a solid-solution alloy that is not age-hardenable, and it is used for hydrochloric acid service at all concentrations up to the boiling point. Jiangyin Jiangnan Metal Co., Ltd. forges NiMo28 into rings, flanges, bars, discs, shafts, sleeves and tube sheets.
Is NiMo28 the same as Alloy B-2?
Yes. NiMo28 is the DIN 17744 designation, W.Nr. 2.4617, for the material designated UNS N10665 and known generically as Alloy B-2. Nimofer® 6928 is the VDM Metals trade name for the same specification. Material forged by Jiangyin Jiangnan Metal Co., Ltd. is described as NiMo28 / 2.4617 / UNS N10665. When ordering, quote UNS N10665 plus the product standard, for forgings ASTM B564, so the requirement is unambiguous. See also our Alloy B-2 forgings page.
What is the chemical composition of NiMo28?
Molybdenum 27.0 to 29.0%, nickel balance (approximately 66 to 70%), chromium 1.0% max, cobalt 1.0% max, iron 2.0% max, manganese 1.0% max, silicon 0.10% max, carbon 0.02% max, phosphorus 0.04% max and sulfur 0.03% max, by weight. Chromium and iron are held low because the alloy does not rely on a passive oxide film and because iron reduces resistance in hot hydrochloric acid. Every heat is supplied with a ladle analysis on the EN 10204 mill certificate.
Which acids does NiMo28 resist, and where must it not be used?
NiMo28 resists hydrochloric acid at all concentrations from room temperature to the boiling point, plus sulfuric, phosphoric, acetic and formic acids, hydrogen chloride gas and non-oxidising chloride salts. It must not be used in oxidising media: nitric acid, ferric chloride, cupric chloride, wet chlorine, hypochlorite or aerated acids. A few parts per million of ferric or cupric ions in hydrochloric acid, or dissolved oxygen carried in with the feed, will raise the corrosion rate sharply. Where the process can move between reducing and oxidising conditions, a nickel-chromium-molybdenum grade such as Alloy C-276 or Alloy 59 is the correct specification.
What heat treatment is correct for NiMo28 forgings?
Solution annealing at approximately 1,065 °C (1,950 °F), held to temperature through section, followed by a rapid water quench. NiMo28 is a solid-solution alloy and is not age-hardened. An ageing treatment precipitates Ni4Mo and beta phase and reduces ductility. The quench must be fast, because slow cooling through roughly 600 to 800 °C causes the same ordering reaction. For the same reason, NiMo28 should not be held in the 600 to 800 °C band in service. Jiangyin Jiangnan Metal Co., Ltd. supplies all NiMo28 forgings solution annealed and rapidly quenched, with the heat treatment record on the certificate.
Why is NiMo28 (Alloy B-2) sometimes replaced by Alloy B-3?
Thermal stability. NiMo28 forms an ordered Ni4Mo (beta) phase when held around 600 to 800 °C, which reduces ductility and can leave a weld heat-affected zone open to preferential attack. Alloy B-3 (UNS N10675) carries deliberate additions that suppress that reaction, so it tolerates thermal cycling and welding better while giving comparable hydrochloric acid resistance. For static, fully annealed, all-welded equipment held away from that temperature band, NiMo28 remains suitable and costs less. Jiangyin Jiangnan Metal forges NiMo28, Alloy B-3 and Alloy B-4.
Can NiMo28 be welded, and which filler metal is used?
Yes. NiMo28 is welded by GTAW, GMAW and SMAW with a matching nickel-molybdenum filler: AWS A5.14 ERNiMo-7 bare wire or AWS A5.11 ENiMo-7 covered electrode. Keep heat input low, keep interpass temperature down, and avoid dwelling in the 600 to 800 °C range. For severe hydrochloric acid duty, a post-weld solution anneal at approximately 1,065 °C followed by rapid quench restores the heat-affected zone. Where that is impractical, specify Alloy B-3 instead.
What are the mechanical properties of NiMo28 forgings?
Typical room-temperature values in the solution-annealed condition are tensile strength 917 MPa (133,000 psi), 0.2% offset yield strength 396 MPa (57,400 psi), elongation 55% in 50.8 mm, and hardness 98 HRB (approximately 241 HV, 168 HB). Density is 9.22 g/cm³ and the melting range is approximately 1,330 to 1,380 °C. Typical values are for design screening. The mill test certificate issued with each forging governs acceptance.
What sizes of NiMo28 forgings can you supply?
Seamless rolled rings from 200 to 3,000 mm outside diameter and up to 800 mm height, round bars 80 to 800 mm diameter up to 6,000 mm long, discs and tube sheets to 2,500 mm diameter and 600 mm thickness, and shafts, sleeves and blocks to 6,000 mm long, with single-piece weights from about 20 to 8,000 kg. Open-die forging needs no dies, so there is no tooling charge and no minimum order quantity by piece, and one-off or prototype parts are economic. For nickel-molybdenum alloys the practical maximum is set by available ingot size, so confirm large sizes with the enquiry.
What testing and certification do you supply?
Every NiMo28 forging ships with an EN 10204 3.1 mill test certificate as standard, showing heat number, chemical analysis, mechanical results, heat treatment record and NDT results. EN 10204 3.2 certification witnessed by TÜV, BV, LR, SGS or DNV is available on request at the time of order. Ultrasonic testing is carried out to EN 10228-3, SEP 1921, ASTM A388 or a nominated customer class, with liquid penetrant examination to ASTM E165 / ASME V Article 6, positive material identification, and intergranular corrosion testing to an agreed procedure where required.
How long does a NiMo28 forging take to produce?
Lead time depends on whether NiMo28 raw stock is on hand and on the size of the forging. Simple rings and discs from stock material typically run 25 to 40 days. Parts needing a fresh melt, ESR remelting, heavy machining or third-party witnessed inspection take longer.
