ASTM A638 660 Stainless Steel Bar
Short Description:
660A refers to a specific condition of the A286 alloy (UNS S66286), which is a high-strength, high-temperature, and corrosion-resistant stainless steel.
660A Stainless Steel Bar:
ASTM A453 Grade 660 is a precipitation hardening austenitic stainless steel widely used for high temperature fastening and bolting materials. The 660A condition of A286 stainless steel is solution annealed, providing a balance of high strength, good formability, and excellent corrosion resistance. This makes it suitable for demanding applications in aerospace, automotive, and industrial sectors where materials must perform reliably under high-stress and high-temperature conditions.Excellent resistance to oxidation and corrosion in high-temperature environments.Good resistance to a variety of corrosive environments, including seawater, mild acids, and alkalis.
