Description
A286 Round Bars (AMS 5731 / AMS 5732 / AMS 5734 / AMS 5737)
A286 Round Bars is designed for applications requiring high strength and good corrosion resistance at temperatures up to 1300° F (704°C). This alloy offers high ductility in notched sections. In fact, the notched rupture strength of alloy A286 is superior to many other commercial alloys with comparable high temperature properties. An advantage of this alloy is that it can be precipitation hardened and strengthened by heat treatments. This makes possible a high degree of uniformity in developing maximum strength, which can be duplicated application after application.
Incoloy Alloy® A286 (also known as A286 stainless steel) is a nickel and iron-based, austenitic superalloy that is useful for applications requiring high strength and corrosion resistance.The mechanical properties of this alloy are developed by suitable solution annealing and precipitation hardening treatments.
This alloy has excellent high temperature oxidation resistance and is designed to maximize creep and stress rupture properties, with some reduction in strength. A286 material can attain high strength levels when aged after cold work and has wide applications in high temperature fasteners and springs. We stock A286 steel in round bar (AMS 5731, 5732, 5737), Sheets, Plates and Coil forms (AMS 5525, 5858) with a variety of cutting and processing services available.
