A-286 Materials - High-Strength Super Alloy

Engineered for aerospace, automotive and industrial applications. Available in round, flat, square and hex.

What is A-286?

Incoloy A-286 (UNS S66286) is an iron-based superalloy known for its high tensile strength and excellent resistance to corrosion and oxidation, even at elevated temperatures. A-286 is a superalloy, but still classified as stainless steel since it’s iron-based with at least 10.5% chromium. Commonly used in aerospace and industrial gas turbine applications, A-286 offers reliable performance in extreme environments.

Common Questions About A-286

Next day shipping is available on in-stock, qualifying orders. Fulfillment times vary for material that requires ordering from a vendor. Reach out to your rep for more information.

A-286 is both a stainless steel and a superalloy. If someone says stainless steel A-286, they’re emphasizing its corrosion resistance and stainless-like properties. If they say superalloy A-286, they’re highlighting its high-temperature strength and use in aerospace, gas turbines, and high-performance fasteners. In short: A-286 is both a stainless steel and a superalloy — an iron-based superalloy that also belongs to the stainless family.

A-286 is similar to certain austenitic stainless steels, particularly Type 310 stainless steel, in terms of its forging, formability, and machinability properties. It’s also comparable to 316/316L stainless steel in terms of aqueous corrosion resistance. Furthermore, A-286 is often compared to Inconel 718 in the context of jet engine applications, where it’s known for its high strength at elevated temperatures.
