FAQ
A-286 is an iron base high temperature alloy (also known as nickel iron chromium superalloy or austenitic precipitation hardening stainless steel) with key additions of molybdenum, titanium, aluminum, and vanadium. UNS S66286 designation. This composition enables excellent high temperature strength, oxidation resistance, and corrosion resistance up to approximately 1300°F (704°C / 700°C continuous service).
A-286 heat resistant alloy wire maintains good mechanical properties and creep resistance up to 1300°F (704°C). For short-term exposure, it can handle slightly higher peaks, but long-term continuous service is recommended below 1300°F to preserve oxidation resistance and prevent excessive creep in high-stress aerospace engine environments.
Yes. Thanks to its high chromium content and molybdenum addition, A-286 offers superior corrosion resistance and pitting resistance compared to standard 300-series stainless steels. It performs well in oxidizing atmospheres, combustion gases, saltwater exposure, and many petrochemical environments, making it ideal for jet engine exhaust systems, offshore equipment, and high-temperature fasteners.
A-286 (iron-nickel-chromium base) provides excellent strength-to-cost ratio and good fabricability up to 1300°F, while being significantly lower in cost than nickel-based Inconel 718 or 625. It offers better high-temperature oxidation resistance than 304/316 stainless, but lower strength above 1300°F compared to Inconel alloys. For most aerospace fasteners, turbine bolts, and gas turbine springs where cost and 700°C performance matter, A-286 is often the preferred choice.
Yes, A-286 age-hardenable alloy wire can be welded, preferably in the solution-annealed condition using inert gas shielded arc (TIG/MIG), resistance, or electron beam welding. Aged material is prone to hot cracking — use low restraint, proper filler (typically A-286 matching), and post-weld heat treatment (solution + age) to restore full precipitation hardening properties and creep resistance.
