Manufacturer of ASTM A320 Stud Bolts in Grade ASTM A320 L7, B8M CLASS 1, B8M CLASS 2 etc.

ASTM A320 B8M Class 2 Stud Bolts fasteners are similar to Grade B8 but instead are manufactured from AISI 316 stainless steel as opposed to AISI 304 stainless steel. Although more expensive, type 316 stainless offers superior corrosion resistance compared to type 304 stainless. Grade B8M Class 1 fasteners require carbide solution treatment, while Class 2 fasteners require an additional strain hardening operation. A320 Grade B8M bolts also do not require an impact test.
