01What is Nimonic 105?
Nimonic 105, also written Alloy 105 and registered as UNS N13021 (Werkstoff 2.4634, BS HR3), is a wrought nickel-cobalt-chromium-base superalloy strengthened by additions of molybdenum, aluminium and titanium.
The alloy sits at the high-temperature end of the Nimonic series. Chromium at 14.0-15.7% provides oxidation and hot-corrosion resistance. Cobalt at 18.0-22.0% and molybdenum at 4.5-5.5% strengthen the matrix in solid solution and slow diffusion at temperature. Aluminium at 4.5-4.9% and titanium at 0.9-1.5% precipitate the gamma-prime phase Ni3(Al,Ti) that carries the load; the aluminium level is the highest in the wrought Nimonic family, which is why Nimonic 105 holds creep strength where Nimonic 90 starts to fall away.
That same gamma-prime content makes the alloy demanding to process. It has a narrow hot-working window, it must be machined in the fully heat-treated condition at 320-385 HV, and it is not suitable for conventional fusion welding. For a buyer, this means Nimonic 105 parts should be designed as one-piece forgings wherever the geometry allows.
Jiangyin Jiangnan Metal Co., Ltd. supplies Nimonic 105 as forged product only: open-die forgings and seamless rolled rings. Forging closes porosity from the ingot, breaks down the as-cast structure and aligns grain flow with the principal stress direction in blade blanks, discs, rings and shafts.

03Why designers specify Nimonic 105
- Creep strength to 950 °C. Developed for sustained load-bearing service at 850-950 °C, the range that covers gas turbine blade and disc duty and ultra-supercritical steam turbine blading.
- High gamma-prime volume fraction. Aluminium at 4.5-4.9% plus titanium at 0.9-1.5% gives more Ni3(Al,Ti) precipitate than Nimonic 80A or 90, so rupture life at temperature is longer.
- Oxidation resistance from Cr + Al. The chromia scale is reinforced by aluminium, which is the main reason the alloy survives long exposure in hot combustion gas.
- Solid-solution stability. Cobalt and molybdenum slow diffusion, so the precipitate coarsens more slowly and the alloy holds its properties through long overhaul intervals.
- Room-temperature strength is retained. Certified minima of 1,140 MPa tensile and 776 MPa yield mean the part is not weak when cold, which matters for bolted and shrink-fit assemblies.
- Forgeable into large one-piece sections. Rings, discs and blade blanks can be produced with continuous grain flow, avoiding the welded joints the alloy does not tolerate.
Where not to use it. Nimonic 105 is not a corrosion alloy for wet acid service, and it is not a weldable structural grade. For aqueous corrosion use Hastelloy C-276 or Alloy 59. Where a hot-section part must be welded, Inconel 617 or Nimonic 263 are the usual alternatives.
04Nimonic 105 compared with 90, 80A, 263 and Waspaloy
Procurement teams usually arrive at Nimonic 105 after ruling out a cheaper grade. The table sets out the trade-off: every step up in temperature capability costs forgeability, machinability and weldability.

08Heat treatment and the Nimonic 105 temperature map
Two heat-treatment routes are recognised, and the choice is driven by service temperature, not by convenience. Route A is the three-stage cycle for parts that run hot for a long time. Route B is the shorter two-stage cycle for parts that run below about 700 °C, where tensile strength, elongation and impact matter more than long-term creep life.
| Route | Step | Temperature | Soak | Cooling |
|---|---|---|---|---|
| A, three stage | Solution treatment | 1,150 °C (2,100 °F) | 4 h | Air cool |
| Second-stage ageing | 1,050-1,065 °C (1,920-1,950 °F) | 16 h | Air cool | |
| Third-stage ageing | 850 °C (1,560 °F) | 16 h | Air cool | |
| B, two stage | Solution treatment | 1,125 °C (2,055 °F) | 4 h | Air cool, freely spaced |
| Ageing | 850 °C (1,560 °F) | 16 h | Air cool |
Source: Jiangyin Jiangnan Metal Co., Ltd. Furnace charts for every cycle are issued with the mill certificate. Route A gives optimum long-term creep strength and ductility for service at 850-950 °C. Route B is used where long-term creep properties are less important and tensile strength, elongation and impact strength are to be raised, for service up to about 700 °C.
Route B loading matters. When Route B is applied, cooling from 1,125 °C must take place freely. Components packed closely in the furnace cool too slowly, and the properties the route was chosen for are lost. We space and record every Route B load for this reason.
09Forging, machining and welding Nimonic 105
Hot working
Nimonic 105 is hot worked between 1,050 and 1,200 °C. The window is narrow and the alloy stiffens quickly as the piece drops out of it, so reheats are frequent and reduction per pass is controlled. Where deformation is heavy, an interstage anneal at 1,150 °C restores workability, followed by air cooling or fluidised-bed quenching. Water quenching is never used, because thermal shock produces severe surface cracking in this alloy.
Machining
All machining is carried out with the material in the fully heat-treated condition. At 320-385 HV, tungsten-carbide-tipped tooling is required; high-speed steel shock-proof tools can be used where the cut is intermittent. In practice this means rigid set-ups, slow surface speeds with heavier depth of cut, positive feed without dwell, sharp tools changed on schedule, and generous coolant. Machining allowances are agreed at quotation, because on this alloy the removal cost is a real part of the finished price.
Welding limitations
Conventional fusion welding of Nimonic 105 is not recommended. TIG and MIG welding can cause microfissuring in both the weld metal and the heat-affected zone, and resistance spot, stitch and seam welding present the same difficulty. Electron beam welding has been used successfully, but the microfissuring risk remains and welding trials should always be run before the process is specified. Flash-butt welding is satisfactory and is in regular production use for turbine components. Design Nimonic 105 parts as one-piece forgings wherever the geometry allows.
Melting practice
Billet is accepted only against documented melt practice. For aerospace and rotating parts we require double-melt VIM + ESR or VIM + VAR material. For industrial and non-rotating work, EAF + VOD + ESR practice is accepted. Single-melt material is not used for rotating parts because of segregation risk.
10How Jiangyin Jiangnan Metal forges Nimonic 105
This is the route run for every Nimonic 105 order. Each stage produces a record that goes into the documentation pack.
Billet acceptance and melt route
Melt certificates and ladle analysis are checked against the governing specification before the billet is cut. VIM + ESR or VIM + VAR for aerospace and rotating parts; EAF + VOD + ESR for industrial work.
Conditioning and uniform pre-heat
Billet surfaces are conditioned and the charge is soaked to a uniform through-temperature. An under-soaked, high gamma-prime alloy cracks on the first blow.
Open-die forging, 1,050-1,200 °C
Press and hammer forging with controlled reduction ratios and frequent reheats. Grain flow is directed along the hoop for rings and along the axis for shafts and blade blanks.
Interstage annealing at 1,150 °C
Applied where deformation is heavy, followed by air cooling or fluidised-bed quenching. Never water quenched.
Ring rolling or upsetting to the finished envelope
Seamless rings are pierced and rolled on 3 m and 6 m mills; discs are upset and punched. Both routes give continuous, uncut grain flow.
Three-stage precipitation heat treatment
Route A or Route B in calibrated furnaces, with recorded time and temperature charts for the whole load and spacing controlled on Route B.
Machining and non-destructive testing
Machined in the fully heat-treated condition with carbide tooling. Ultrasonic testing to EN 10228-3, SEP 1921 or ASTM A388, plus penetrant or magnetic particle inspection as specified.
Marking, certification and packing
Heat number and part identification hard stamped, EN 10204 3.1 certificate issued, or 3.2 counter-signed by TÜV, BV, SGS or Lloyd's Register, then seaworthy packing for export.

15Frequently asked questions about Nimonic 105
What is Nimonic 105?
Nimonic 105 is a wrought nickel-cobalt-chromium-base superalloy, designated UNS N13021 and Werkstoff 2.4634, strengthened by additions of molybdenum, aluminium and titanium. It contains roughly 20% cobalt, 15% chromium, 5% molybdenum, 4.7% aluminium and 1.2% titanium with nickel as the balance. It was developed for load-bearing service up to about 950 °C and combines the high strength of the age-hardening nickel alloys with good creep resistance. Jiangyin Jiangnan Metal Co., Ltd. forges it into rings, discs, blade blanks, shafts and bars.
What is the UNS number for Nimonic 105?
The UNS number for Nimonic 105 is N13021. The alloy is also designated W.Nr. 2.4634 in Germany, BS HR3 in the United Kingdom, MSRR 7017 and MSRR 7018 in aerospace procurement, ISO NW 3021, AFNOR NCKD 20ATv, and by the composition name NiCo20Cr15MoAlTi. It is also written simply as Alloy 105.
What is the maximum service temperature of Nimonic 105?
Nimonic 105 was developed for load-bearing service up to about 950 °C (1,740 °F). The three-stage heat treatment is intended for optimum long-term creep strength and ductility in the 850-950 °C range. Where components run below 700 °C and long-term creep life is not critical, the shorter two-stage treatment is used instead to raise tensile strength, elongation and impact strength.
What is the chemical composition of Nimonic 105?
Nimonic 105 contains 14.0-15.7% chromium, 18.0-22.0% cobalt, 4.5-5.5% molybdenum, 4.5-4.9% aluminium, 0.9-1.5% titanium and 0.003-0.010% boron, with nickel as the balance. Limits are carbon 0.17% max, silicon 1.0% max, manganese 1.0% max, iron 1.0% max, copper 0.2% max, zirconium 0.15% max, sulphur 0.010% max and lead 0.0015% max. The full table is in section 5.
What is the correct heat treatment for Nimonic 105?
Two routes are recognised. Route A is 4 h at 1,150 °C with air cool, then 16 h at 1,050-1,065 °C with air cool, then 16 h at 850 °C with air cool; it gives the best long-term creep strength and ductility for service between 850 and 950 °C. Route B is 4 h at 1,125 °C with air cool, then 16 h at 850 °C with air cool, used up to about 700 °C. On Route B the load must be spaced so that cooling from 1,125 °C is not delayed by close packing.
What is the density of Nimonic 105?
The density of Nimonic 105 is approximately 8.0 g/cm³, or 0.289 lb/in³. Its solidus is about 1,290 °C and its liquidus about 1,345 °C. In the fully heat-treated condition the hardness range is 320-385 HV.
Can Nimonic 105 be welded?
Nimonic 105 is difficult to weld and conventional fusion welding is not recommended. TIG and MIG welding can cause microfissuring in both the weld metal and the heat-affected zone, and resistance spot, stitch and seam welding present the same difficulty. Electron beam welding has been used successfully but the microfissuring risk remains, so welding trials should always be run before the process is specified. Flash-butt welding is satisfactory and is in regular production use for turbine components. Design Nimonic 105 parts as one-piece forgings wherever possible.
How is Nimonic 105 machined?
Nimonic 105 should be in the fully heat-treated condition for all machining operations. The high hardness range of 320-385 HV requires tungsten-carbide-tipped tooling; high-speed steel shock-proof tools can be used where the cut is intermittent. Use rigid set-ups, positive feed with no dwell, generous coolant and slow surface speeds with heavier depth of cut. Jiangyin Jiangnan Metal Co., Ltd. supplies Nimonic 105 as-forged, rough machined to an agreed allowance, or finish machined to drawing.
What is the forging temperature range for Nimonic 105?
Nimonic 105 is hot worked between about 1,050 and 1,200 °C. Where deformation is heavy, an interstage anneal at 1,150 °C followed by air cooling or fluidised-bed quenching restores workability. Water quenching is not used, because thermal shock can produce severe surface cracking. Reheats are frequent, because the alloy loses workability quickly as the piece falls out of the window.
What is the difference between Nimonic 105 and Nimonic 90?
Nimonic 90 (UNS N07090, W.Nr. 2.4632) is a nickel-chromium-cobalt alloy strengthened by titanium and aluminium, rated for service to about 920 °C. Nimonic 105 (UNS N13021, W.Nr. 2.4634) adds 4.5-5.5% molybdenum for solid-solution strengthening and raises aluminium to 4.5-4.9%, which increases the gamma-prime volume fraction and lifts creep strength and oxidation resistance to about 950 °C. The penalty is that Nimonic 105 is harder to forge, harder to machine and not suitable for fusion welding. Full comparison in section 4.
What is Nimonic 105 used for?
Nimonic 105 is used for gas turbine blades and discs, hot-section forgings and ring sections, turbine spacer rings, high-temperature bolts and fasteners, and blading for ultra-supercritical steam turbines. It also serves in hot-working tools, high-temperature springs, furnace and heat-treatment equipment components, boiler tube supports, die-casting inserts and cores, and automotive exhaust valves.
Which standards and specifications cover Nimonic 105 forgings?
Nimonic 105 billets, bars, forgings and parts are covered by BS HR3, which specifies the nickel-cobalt-chromium-molybdenum-aluminium-titanium heat-resisting alloy. Aerospace procurement generally invokes MSRR 7017 and MSRR 7018. Other listings are ISO NW 3021, AFNOR NCKD 20ATv and AECMA prEN 2179-2181. Jiangyin Jiangnan Metal Co., Ltd. also delivers Nimonic 105 forgings against ASTM B637 acceptance and against customer drawings and end-user specifications where those govern.
What forged shapes can be made in Nimonic 105?
Jiangyin Jiangnan Metal Co., Ltd. produces Nimonic 105 as seamless rolled rings from 200 to 2,500 mm outside diameter, forged discs from 150 to 1,600 mm diameter, turbine blade and disc blanks, shafts and spindles from 60 to 600 mm diameter and up to 4,000 mm long, round bars from 20 to 400 mm diameter, flanges, sleeves, bushings, hollow bars, blocks, tube sheets and nozzles, in single-piece weights from 5 kg to about 3,000 kg.
Who supplies Nimonic 105 open-die forgings in China?
