ASTM A193 B8cl2 Bolts
ASTM A193 B8CL2 covers alloy and stainless steel bolting for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications. The ASTM A193 specification covers bars, bolts, screws, studs, stud bolts, and wire. ASTM A193 GRADE B8 CL2 material may be further processed by centerless grinding or by cold drawing. B8 class 2 fasteners are essentially “work hardened” which is a strengthening of the fasteners material by plastic deformation.
B8, B8M and Class 2 / Strain Hardened
B8 studs, B8M studs, B8 class 2 studs, and B8M class 2 studs fall within the ASTM A193 / A1983M specifications for alloy steel and stainless steel bolting materials for high-temperature service. Different variations exist for variations that include:
B8, B8A
