Stainless Steel A286 AMS 5853
AMS 5853 is a sub-type specification of Stainless Steel A286 that comes in an electrode-melted, solution treated and work-strengthened form. The strength of the material is raised using cold-reducing techniques, typically ranging from 15% to 17%. The resulting tensile strength is 160 ksi at up to 1000 °F (540 °C). Moreover, this specification carries excellent oxidation resistance at temperatures up to 1200 °F (650 °C).
Tech Steel & Materials offers AMS 5853 in the form of bars and wires. The specification can be vacuum arc remelted, or electroslag remelted if needed. Thanks to its unique properties, AMS 5853 finds use in various industries, mostly for fasteners in high-temperature environments, but also springs, jet engine components, supercharger components, etc. Other uses include high-temperature afterburner parts, tanks, piping, pumps, and heat exchangers.
Despite the excellent strength and hardness, AMS 5853 can be readily formed and cold-worked more. Also, the alloy can be welded using standard procedures, gas tungsten arc, gas metal arc, and shielded metal arc. Any nickel-based steel can be used as filler metal, but the filler wire of the same specification is recommended. For optimal strength, the weld should be convex. Also, it is recommended to age the parts after welding to minimize cracking.
