ASTM A 453 GR 660 Class B Stud Bolts are manufactured using an austenitic stainless steel alloy consisting largely of iron, nickel (24–27%), chromium (13–17%), manganese, and molybdenum, with trace elements for increased strength. They are solution treated and precipitation hardened. Mechanical properties consist of minimum tensile strength of 125 ksi, yield strength of 105 ksi, and elongation of 15%. They are highly mechanically stable and resistant to corrosion at high temperatures and are suitable for use in high-stress applications. They also have good ductility, hardness, and oxidation resistance under severe conditions.
