What is ASTM A 453 GR 660 Class B Stud Bolts?
ASTM A453 Grade 660 Class B stud bolts are created from a high-strength, precipitation-hardened alloy (similar to A-286) that uses iron as the primary metal. The normal chemical composition has Nickel (24-27%), Chromium (13.5-16%), Molybdenum (1-1.5%), Titanium (1.9-2.35%), Vanadium (0.1-0.5%), small amounts of Boron and the remaining portion is Iron. The presence of these elements gives them exceptional strength and oxidation resistance at elevated temperature levels. Mechanical properties are given as a minimum tensile strength of 760 MPa, yield strength of 585 MPa, an ultimate elongation of 15%, and a reduction in area of 20% which all indicate exceptional performance in economically demanding applications.
