astm a638 660 type 1 Specification
A286 stainless steel Fasteners are referred as high temperature bolting with co-efficient expansion similar to Austenitic Stainless Steel. A286 material specification is achieved by producing A286 steel in Argon oxygen decarburization (AOD) or vacuum Induction Melting Process that is further refined by Vacuum Arc Refining (VAR) or Electro Slag Refining (ESR) used for high nickel alloys like incoloy alloys. Comparable to incoloy, A286 can be age hardened with both oil quench and liquid quench conditions. Unlike other precipitation hardening steels, this A286 Steel requires Stress Rupture Testing with 100 hours minimum time to rupture. High temperature and low stress applications, good corrosion resistance at high temperatures are some of the most A286 Stainless Steel Properties. A286 steel is available in both solution treated condition and age hardened conditions.
