Product Description
ASTM A453 Grade 660 is a material specification for studs bolts, nuts and hex nuts other fasteners, intended for use in high temperature bolting applications. There are four Classes for ASTM A453 Grade 660: A453 GR.660A , A453 GR.660B ,A453 GR.660C ,A453 GR.660D, each designated with different tensile and stress rupture properties. A453 Grade 660 fasteners are used in bolting boilers, pressure vessels, pipeline flanges and valves, intended for high temperature service. ASTM A453 grade 660 material is chemically equivalent to ASTM B638 grade 660 stainless steel alloy, also known by alloy A286 and UNS S66286, heat treated to achieve properties defined in ASTM A453 specification.
ASTM A453 Grade 660 stud bolt is a precipitation hardening austenitic stainless steel widely used for high temperature fastening and bolting materials. Its relatively high nickel content for a stainless steel means that is sometimes categorized as a nickel alloy. The grade is commonly used for operating temperatures up to 700°C (1300°F).
We are professional A453 Grade 660 Stud bolt and ASTM A453 Gr 660 Hex nuts manufacturer and exporter in China.
Material Grade in A453: Grade 660 /S66286 ,Grade 651/S63198 ,Grade 662 /S66220 ,Grade665 /S66545 ,Grade668 /S66285.
