What Is ASTM A193 Grade B8M?
ASTM A193 is a standard that covers high-temperature bolting materials made from alloy and stainless steel for pressure vessels, valves, flanges, and fittings. The Grade B8M specification refers to bolts made from Type 316 stainless steel, which includes molybdenum to improve corrosion resistance in chloride-heavy and acidic environments.
B8M Bolt Classes:
- Class 1: Strain hardened
- Class 2: Solution treated and strain hardened (higher mechanical performance)
Both variants are widely used in critical applications where corrosion and mechanical fatigue are major concerns.
Key Features of ASTM A193 B8M Bolts
- Made from austenitic 316 stainless steel
- Excellent resistance to pitting, crevice corrosion & stress corrosion cracking
- High mechanical strength (tensile & yield)
- Performs well in high-temperature and high-pressure systems
- Non-magnetic and weldable
- Available with full certification and traceability
