Incoloy A-286 (UNS S66286, equivalent to Chinese GH2132) is an iron-nickel-chromium precipitation-hardening superalloy. Below 700 °C it offers high strength and good oxidation resistance at lower cost than nickel-base superalloys, and is among the most heavily used grades for aerospace fasteners and turbine parts.
As a manufacturer and global exporter of special alloys since 2012, Shanghai Hangbo Alloy Group Co., Ltd. supplies Incoloy A-286 as round bars (φ2–600 mm, up to 12 m), plates & sheets (0.5–100 mm thick, up to 2500 mm wide), forgings & rolled rings (up to 7500 kg, 3500 mm OD), machined parts to your drawings, welding wire & coils (1.0–5.0 mm) — all with EN 10204 3.1 certified material test reports.

Frequently asked questions
What is the standard heat treatment for A-286?
A common cycle is solution treatment at 980 °C for 1 hour with oil quench or air cool, followed by ageing at 720 °C for 16 hours and air cooling (AMS 5731/5732). Parts needing better creep performance may use a 900 °C solution plus a 720 °C/650 °C double age.
What forms and sizes are available?
We supply Incoloy A-286 as round bars (φ2–600 mm, up to 12 m), plates & sheets (0.5–100 mm thick, up to 2500 mm wide), forgings & rolled rings (up to 7500 kg, 3500 mm OD), machined parts to your drawings, welding wire & coils (1.0–5.0 mm). Custom lengths, tolerances and machining to drawing are available on request.
What is the MOQ and lead time?
MOQ is flexible — trial orders from a single piece are welcome. Stock sizes ship in 3–7 days; custom forgings and machined parts typically 15–35 days depending on quantity and process.
Can you provide third-party inspection and shipping to my port?
Yes. SGS / BV / TUV or your nominated inspector can witness all tests before shipment. Full export documentation is provided, and we ship worldwide by sea or air on FOB, CIF or DDP terms.
