Learn about our high-performance, age hardenable, Iron-Nickel-Chromium Alloy, A286.
A286 Overview
Alloy A286 is an age-hardenable iron-nickel-chromium alloy developed for use in environments that demand both high strength and reliable corrosion resistance at temperatures reaching up to 700°C (1290°F). Its robust mechanical properties make it well-suited for components in aircraft and industrial gas turbines. Additionally, it is commonly employed in the offshore oil and gas sector, as well as in fasteners and automotive engine parts exposed to elevated heat and stress conditions.
Ageing process – heat treatment to be held 705 – 760 °C (1300 – 1400 °F) for 16 hours and then air cooled.
