ASTM A453 Grade 660 Stud Bolts

ASTM A453 Grade 660 Stud Bolts is a precipitation hardening stainless steel fastener. Austenitic alloy astm a453 grade 660 nuts are known for its impressive tensile strength properties even when exposed to high temperatures. Therefore these stainless steel ASTM A453 Grade 660 bolts could be used up to a temperature of up to 700°C.

 The UNS 66286 Threaded Rod is sold under other trade names such as UNS S66286, A-286 alloy and Alloy 660. The alloy gains its high tensile strength from a high degree of uniformity. The ASTM A286 Bolts has an impressive minimum yield strength of 105,000 psi. Since the SA 453 Grade 660 Material is able to maintain its high strength even at elevated temperatures, these fasteners and bolts are commonly used in high temperature settings such as Jet engines, Turbocharger components as well as gas turbines.

Apart from conforming to the chemical composition requirements of the  ASTM A453 specification, the mechanical properties of the ASTM A453 Gr 660 Stainless Steel Bolt are also to adhere to the specification. This is why, the A286 Stainless Steel Fasteners have to be subjected to several tests such as tension test, stress rupture test, and hardness test. Materials produced under this specification, including the ASTM A453 Gr 660 Cl.A Stud bolt has to conform to elongation,  reduction of area, yield strength, tensile strength in addition to the Brinell hardness, and Rockwell hardness requirements. Hardening and solution treatment requirements for each material class i.e.  A453 Gr 660 Class A/B/C/D Stud Bolts are also specified.
