A286 Bolts Specification

ASTM A453 grade 660 Fasteners are referred as high temperature bolting with co-efficient expansion similar to Austenitic Stainless Steel. A453 material specification is achieved by producing A453 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, ASTM A453 can be age hardened with both oil quench and liquid quench conditions. Unlike other precipitation hardening steels, this ASTM A453 grade 660 fasteners require 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 ASTM A453 Stainless Steel Properties. ASTM A453 steel is available in both solution treated condition and age hardened conditions.
