14/03/2014

A286 is a precipitation hardening, austenitic stainless steel designed for use at temperatures up to 1300°F (704°C), where high tensile strength, excellent creep strength and good corrosion resistance are required.

Hague Fasteners are experts in the manufacture of all types of A286 fasteners, from A286 Hex Nuts, A286 Hex Bolts & A286 Studbolts through to complete special fasteners made to Drawings.

Hague Fasteners manufactured Special Fasteners in specification ASTM A453 660 are used in all types of applications including jet engines, gas turbines, and super-charger components.

A286 is also used extensively in the oil and gas industry, and in high-strength non-magnetic and cryogenic applications. It is austenitic at all temperatures.

HEAT TREATMENT Two heat treatments are commonly used for this alloy.

For high stress rupture strength: Solution treat at 1800°F (982°C) for 1 hr, rapid cool, age at 1325°F (718°C) for 16 hrs, air cool. (e.g., ASTM A638 Grade 660 Type 2; ASTM A453 Grade 660 Class B; ASTM A891 Type 2; AMS 5732)

For high room temperature tensile strength and stress rupture ductility: Solution treat at 1650°F (899°C) for 2 hr, rapid cool, age at 1325°F (718°C) for 16 hrs, air cool. (e.g., ASTM A638 Grade 660 Type 1; ASTM A453 Grade 660 Class A, ASTM A891 Type 1; AMS 5737)
