Direct answer
UNS N06950 is a nickel-chromium-molybdenum-iron alloy, also known as Alloy G-50 or Hastelloy® G-50, containing a minimum of 50% nickel, 19–21% chromium, 8–10% molybdenum and 15–20% iron, with carbon held to 0.020% maximum. It was developed as an economical alternative to Alloy C-276 for oil and gas producers handling sour gas, and resists sulphide stress cracking (SSC) and hydrogen-induced cracking (HIC) in H₂S-bearing environments.
Jiangyin Jiangnan Metal Co., Ltd., an open-die forging factory at No. 1 Chengxiqiao Road, Zhouzhuang Town, Jiangyin City, Jiangsu Province, China, forges UNS N06950 into seamless rolled rings, flanges, discs, shafts, sleeves, bushings, tube sheets and round bars to ASTM B564, in the solution-annealed condition, with EN 10204 3.1 or 3.2 mill test certificates.

§1 What is UNS N06950?
UNS N06950 is a solid-solution nickel alloy. Chromium at 19–21% forms the passive oxide film that provides resistance in oxidising conditions. Molybdenum at 8–10% provides resistance in reducing acids and to pitting and crevice attack in chloride-bearing brines. Iron at 15–20% replaces part of the nickel content, which makes the grade cheaper than a full Ni-Mo-Cr alloy such as C-276 while retaining most of the sour-service performance.
The grade was introduced for producers of sour gas as a lower-cost substitute for Alloy C-276. It improves on Alloy G-3 where high hydrogen sulphide concentrations occur together with carbon dioxide and chlorides. In 15% hydrochloric acid and in hydrogen sulphide stress-corrosion-cracking tests, its elevated-temperature corrosion resistance falls between G-3 and C-276. The alloy was developed for consistent manufacture of tubular products and is used for downhole tubing, drill collars, hangers and wellhead hardware.
UNS N06950 is a solid-solution alloy and is not strengthened by ageing. Strength above the annealed level is produced by cold work. Specifying “solution treated and aged” for N06950 on a purchase order is a specification error. Jiangyin Jiangnan Metal Co., Ltd. queries this with the purchaser before releasing a forging.

§6 Corrosion resistance and sour service
UNS N06950 is specified for deep, hot, sour gas wells where carbon and low-alloy steels crack and where 13Cr and duplex grades have insufficient margin. Behaviour in the principal service environments is summarised below.
- Hydrogen sulphide (H₂S). Resists sulphide stress cracking (SSC) and hydrogen-induced cracking (HIC). Performance improves on Alloy G-3 where high H₂S is combined with CO₂ and chlorides.
- Chlorides. The nickel matrix gives high resistance to chloride stress-corrosion cracking; 8–10% molybdenum handles pitting and crevice attack in produced brines.
- Reducing acids. In 15% hydrochloric acid at elevated temperature, resistance sits between Alloy G-3 and Alloy C-276. Where hot reducing acid governs rather than sour gas, C-276 or Alloy 59 gives a higher margin.
- Oxidising media. The 19–21% chromium level provides good resistance to oxidising conditions and to CO₂-driven corrosion.
- Intergranular attack. Carbon at 0.020% maximum limits grain-boundary carbide precipitation, so the alloy tolerates welding and hot work without severe sensitisation. Intergranular corrosion testing to ASTM G28 can be added to the order.
§7 Melting route, forging and heat treatment
Melting
UNS N06950 is a low-carbon nickel alloy and is normally supplied from a vacuum induction melted plus electroslag remelted (VIM + ESR) route, which controls carbon, sulphur and gas content and gives the ingot soundness needed for large ring blanks. VIM + VAR, or an EAF + AOD/VOD + ESR route, is available where the purchase order permits it. State the required melting practice on the enquiry. It is frequently mandated by oil and gas end-user specifications.
Forging
Forging is carried out in the hot-working range with sufficient reduction to break down the as-cast structure through the full section. The working window for this alloy is narrower than for steel and the flow stress is higher. Finishing below temperature produces a duplex grain structure that appears as scattered ultrasonic indications. Production practice is controlled reheats with pyrometer records and a final solution anneal on every piece.
Heat treatment
| Operation | Temperature | Cooling | Result |
|---|---|---|---|
| Solution anneal | ≈ 1149 °C (2100 °F) | Rapid cool or water quench | Standard delivery condition; carbides in solution, uniform grain |
| Age / precipitation hardening | Not applicable. UNS N06950 is a solid-solution alloy and is not age hardened. | ||
| Strengthening above annealed level | By cold work only. Specify the required strength level and the applicable hardness cap on the order. | ||
| Stress relief after machining | By agreement. Must not compromise the sour-service condition; refer to the governing specification. | ||

§11 UNS N06950 compared with other nickel alloys
The table below compares UNS N06950 with the four grades most often specified as alternatives to it. The variables that govern the selection are molybdenum level, iron content and cost.
| Alloy | UNS | Ni % | Cr % | Mo % | Fe % | Density | Relative cost | Best suited to |
|---|---|---|---|---|---|---|---|---|
| Alloy G-50 | N06950 | 50 min | 19–21 | 8–10 | 15–20 | 8.17 | Medium | Sour gas: high H₂S with CO₂ and chlorides |
| Alloy G-3 | N06985 | ~44 | 21–23.5 | 6–8 | 18–21 | 8.3 | Lower | Milder sour service, phosphoric acid |
| Alloy C-276 | N10276 | ~57 | 14.5–16.5 | 15–17 | 4–7 | 8.89 | High | Severe reducing acids, high H₂S duty |
| Alloy 625 | N06625 | 58 min | 20–23 | 8–10 | 5 max | 8.44 | High | Seawater, high temperature, cladding |
| Alloy 825 | N08825 | 38–46 | 19.5–23.5 | 2.5–3.5 | 22 min | 8.14 | Lower | Sulphuric acid, milder oilfield duty |

Request a current quotation. All five grades are forged at our plant; see the related-grade links at the foot of this page.
Selection summary
For sour gas containing high H₂S together with CO₂ and chlorides, UNS N06950 is normally the economic selection. It was developed for that duty and costs less than C-276 because iron replaces part of the nickel content. For hot reducing acids such as hydrochloric acid, or sulphuric acid with contaminants, the 15–17% molybdenum in C-276 gives a higher margin. In mild sour environments, G-3 or 825 will usually qualify at lower cost. Alloy 625 is specified where seawater and elevated temperature govern rather than H₂S. Confirm the selection against NACE MR0175 / ISO 15156-3 for the specific service envelope.
§12 Machining, welding and forming
Machining
Machining behaviour is similar to austenitic stainless steel. The alloy work-hardens, so use positive rake tooling, rigid setups and a heavy positive feed, and avoid dwelling in the cut. Allow adequate machining stock on forgings.
Welding
Welded by GTAW, GMAW and SMAW using matching or over-alloyed filler. Keep heat input and interpass temperature controlled. For sour service, weld procedure and PWHT requirements are governed by NACE MR0175 / ISO 15156-3 and your project spec.
Hot and cold forming
Formed by conventional methods. Cold work raises strength and hardness. Check the resulting hardness against the applicable sour-service limit before accepting cold-formed parts. Soft die materials such as bronze reduce galling.
Surface condition
Forgings supplied as-forged and shot-blasted, rough machined, or finish machined to drawing. Pickling and passivation available on request.

§14 Frequently asked questions about UNS N06950
What is UNS N06950?
UNS N06950 is a nickel-chromium-molybdenum-iron alloy, commonly called Alloy G-50 or Hastelloy® G-50, containing a minimum of 50% nickel, 19–21% chromium, 8–10% molybdenum and 15–20% iron with carbon held to 0.020% maximum. It was developed as a lower-cost alternative to Alloy C-276 for oil and gas producers handling sour gas, and it resists sulphide stress cracking and hydrogen-induced cracking in H₂S-bearing environments. Jiangyin Jiangnan Metal Co., Ltd., an open-die forging factory at No. 1 Chengxiqiao Road, Zhouzhuang Town, Jiangyin, Jiangsu, China, forges UNS N06950 into seamless rolled rings, flanges, discs, shafts, sleeves, bushings, tube sheets and round bars.
Is UNS N06950 the same as Hastelloy G-50?
Yes. UNS N06950 is the Unified Numbering System designation for the alloy sold under the trade names Hastelloy® G-50 and Alloy G-50. Hastelloy® is a registered trademark of Haynes International, Inc. Material produced by Jiangyin Jiangnan Metal Co., Ltd. is correctly described as UNS N06950 or Alloy G-50, the same generic chemistry, manufactured independently and not affiliated with or endorsed by the trademark holder.
What is the chemical composition of UNS N06950?
The specification range Jiangyin Jiangnan Metal Co., Ltd. forges to is: nickel 50% minimum (balance), chromium 19–21%, iron 15–20%, molybdenum 8–10%, cobalt 2.50% maximum, manganese 1.0% maximum, silicon 1.0% maximum, tungsten 1.0% maximum, niobium 0.50% maximum, copper 0.50% maximum, aluminium 0.40% maximum, phosphorus 0.040% maximum, carbon 0.020% maximum and sulphur 0.015% maximum. Every heat is supplied with a ladle analysis on the mill certificate; product analysis can be added on request.
What are the mechanical properties of UNS N06950 forgings?
In the solution-annealed delivery condition Jiangyin Jiangnan Metal Co., Ltd. certifies tensile strength of 760 MPa (110,000 psi) minimum, 0.2% offset yield strength of 700–860 MPa (102,000–125,000 psi), elongation of 20% minimum in 50 mm, and hardness of 31 HRC maximum. Values are room-temperature minima taken from a test coupon representing the forging.
How is UNS N06950 heat treated?
UNS N06950 is a solid-solution alloy, not a precipitation-hardening one, so it is solution annealed at approximately 1149 °C (2100 °F) and then rapidly cooled or water quenched. It is not age hardened; additional strength is obtained by cold work rather than by ageing. Jiangyin Jiangnan Metal Co., Ltd. supplies forgings in the solution-annealed condition unless the purchase order states otherwise.
Which standards cover UNS N06950 forgings?
Forgings are normally ordered to ASTM B564 / ASME SB-564 for nickel alloy forgings. Rod and bar are covered by ASTM B581 and plate, sheet and strip by ASTM B582. For H₂S-containing oil and gas service the material is evaluated against NACE MR0175 / ISO 15156-3. Inspection documents are issued to EN 10204 type 3.1 or, where a third party is nominated, type 3.2.
Is UNS N06950 suitable for sour service under NACE MR0175?
UNS N06950 was developed specifically for sour gas duty and resists sulphide stress cracking and hydrogen-induced cracking in H₂S-bearing environments. Acceptability for a given well or process stream still depends on H₂S partial pressure, chloride content, pH, temperature and the delivered hardness and condition, all of which must be assessed against NACE MR0175 / ISO 15156-3 and stated on the purchase order. Send Jiangyin Jiangnan Metal Co., Ltd. your service envelope and the applicable material data sheet with the enquiry.
How does UNS N06950 compare with Hastelloy C-276 and G-3?
UNS N06950 was introduced as an economical alternative to Alloy C-276 for sour gas producers. Its corrosion resistance at elevated temperature sits between Alloy G-3 (UNS N06985) and Alloy C-276 (UNS N10276) in 15% hydrochloric acid and in hydrogen sulphide stress corrosion cracking tests, and it outperforms G-3 where high H₂S is combined with carbon dioxide and chlorides. C-276 carries roughly 15–17% molybdenum against 8–10% in N06950 and is the stronger choice in severe reducing acids, at higher cost.
What size UNS N06950 forgings can be produced?
Jiangyin Jiangnan Metal Co., Ltd. forges diameters from 80 mm to 6000 mm, lengths from 100 mm to 12000 mm and single-piece weights from 10 kg to 15,000 kg, using open-die hammers up to 9 tonnes, a hydraulic press of 5000 tonnes and seamless ring-rolling mills up to 6 m. The practical maximum size for UNS N06950 depends on the ingot available for the heat, so confirm the envelope for your part at enquiry stage.
What testing and certification are supplied with UNS N06950 forgings?
Standard scope is chemical analysis, room-temperature tensile test, hardness survey and ultrasonic examination to EN 10228-3, SEP 1921 or ASTM A388 to the acceptance class stated on the order, documented on an EN 10204 3.1 mill test certificate. Liquid penetrant examination, positive material identification, intergranular corrosion testing, impact testing and EN 10204 3.2 certification witnessed by a nominated third party such as TÜV, SGS, BV, Lloyd's Register or DNV are available on request.
What is the lead time for UNS N06950 forgings?
Typical lead time is 25 to 45 days from drawing approval for made-to-order UNS N06950 forgings, driven mainly by nickel alloy raw material availability. Repeat parts and small rings ordered against an existing heat can be shorter. Confirm the current date with Jiangyin Jiangnan Metal Co., Ltd. at sales@steelforgepieces.com or +86 189 2135 9659.
