ASTM A193 Grade B8M

ASTM A193 Grade B8M

ASTM A193 Grade B8M is a standard material specification for high tensile 316/316L stainless steel bolts, screws, studs or other external threaded fasteners for high-temperature, high-pressure service and other special purpose applications.

A193 Grade B8M is chemically equivalent to AISI 316/316L stainless steel with improved strength, categorized in two different tensile classes namely class 1 and class 2.

A193 Grade B8M class 1 bolts are carbide solution treated with maximum tensile strength requirement of 75 ksi or 515 MPa, yield 30 ksi or 205 MPa, and maximum hardness of 223 HBW whereas Grade B8M class 2 bolts are carbide solution treated and strain hardened to achieve higher tensile requirement of 110 ksi or 760 MPa and 95 ksi or 655 MPa and maximum hardness of 321 HBW or 35HRC. Grade B8M fasteners are used for high strength pipeline bolting applications.
