A-286 Stainless Steel

Best Stainless is proud to offer our customers the high-temperature alloy of choice, A-286 Stainless Steel.  A-286 is an iron-nickel-chromium-based austenitic alloy that is age-hardening, has high strength, and maintains performance across a broad range of temperatures.

While still more difficult to work with than stainless steels such as 316 and 310, A-286 can still be cold-worked with satisfactory results.  When compared with other nickel or cobalt-based high-temperature alloys A-286 is considerably easier to machine.  It can also be solution annealed and age hardened for various applications, and is often treated to provide superior creep strength.  Best Stainless offers a number of value-added surfaces, including age hardening and solution annealing.

A-286’s most notable virtue is its wide temperature range.  It can maintain high strength when faced with continuous exposure from -320 to 1300°F (700°C) and remains resistant to oxidation even when continuously exposed to as much as 1500°F and in the face of intermittent temperatures as high as 1800°F.  This impressive temperature tolerance lends itself to numerous applications in high-heat environments such as jet engine and steam turbine components, and fasteners and springs in high-temperature settings.  It is also useful in cryogenics and other low-temperature environments.

Best Stainless can provide customers with several stock shapes and is the industry choice for projects requiring longer stock lengths, up to 28’.
