Introduction to Alloy 660 Fasteners

Alloy 660 fasteners, also known as ASTM A453 Grade 660 fasteners, are premium high-temperature fastening solutions designed for extreme service conditions. These precipitation-hardening stainless steel fasteners combine excellent mechanical strength with outstanding corrosion resistance, making them ideal for aerospace, nuclear, and high-temperature industrial applications. At RAYCHIN LIMITED, we specialize in manufacturing Alloy 660 bolts, Alloy 660 nuts, Alloy 660 screws, and Alloy 660 washers that deliver exceptional performance in temperatures up to 700°C (1300°F).
