ASTM A453 GR 660 Class A Fasteners are alloy steel fasteners that are heat-treated to attain high strength and great toughness. The chemical composition of these fasteners generally consists of carbon, manganese, chromium, molybdenum, and vanadium, giving them improved hardness and wear resistance. Mechanically, these fasteners possess tensile strength of nearly 110 ksi (760 MPa) and yield strength of around 90 ksi (620 MPa). They also show good impact resistance and dimensional stability under high temperatures. The controlled heat treatment process ensures homogeneous mechanical properties, and hence, these fasteners are appropriate for heavy-duty and high-stress conditions.
