ASTM A193 B8M Bolts

The ASTM A193 Grade B8M specification is the controlling ASTM standard that gives the specifications of high tensile bolting material manufactured using 316/316L stainless steel. This standard spells out the required chemical composition, mechanical properties, hardness, preferential heat treatment, product marking, and certification of fasteners that are to be used as service in high temperature, high-pressure, or other special applications. These bolts are applicable in the critical practice in pressure vessels, valves, flanges and fittings.

ASTM A193 Grade B8M fasteners have been separated into two unique property classes depending on the tensile strength they need. Class 1 material is carbide solution treated 316 stainless steel with tensile strength at least 75 ksi (515 Mpa), a yield strength at least 30 ksi (205 Mpa), and a hardness of up to 223 HBW. Class 2 metal is strain hardened to much greater levels of higher properties with required minimum tensile strength of 125 ksi (860 MPa), 100 ksi (690 MPa) of yield and 321 HBW (35 HRC) of maximum hardness.
