B8M, B8M CLASS 2
What is B8M, B8M CLASS 2?
B8M is a type of austenitic stainless steel fastener material known for its superior corrosion resistance. Made from 316 stainless steel (UNS S31600) specific process steps and testing are required to produce consistent uniform product that can meet the needs of the process industry.
Grade B8M is referenced in both the ASTM A193 and ASTM A320 Specifications. ASTM A193 Grade B8M is designed for high temperature service, while ASTM A320 Grade is designed for low temperature service. Both specifications offer B8M Class 2 as a variant of B8M that has been strain-hardened to achieve higher tensile strength, offering both robustness and durability for demanding applications. These materials are specifically engineered for environments that face exposure to corrosive substances and extreme temperatures.
System 22 stocks ASTM A193 B8M Class 1 and Class 2 threaded rod, studs, hex bolts, and socket head cap screws.
Key Properties
and Advantages
1. Excellent Corrosion Resistance
The addition of molybdenum in B8M gives it superior resistance to pitting and crevice corrosion, making it ideal for use in chemical processing, marine applications, and environments with high chloride exposure.
2. High Strength in Class 2
B8M Class 2 fasteners undergo strain hardening, enhancing their tensile and yield strength. This property allows for use in applications that demand more load-bearing capacity and mechanical robustness.
3. Temperature Performance
B8M and B8M Class 2 retain their mechanical properties under a wide range of temperatures, ensuring consistent performance even in environments with significant thermal variation.
4. Durability & Longevity
Thanks to their corrosion resistance and mechanical properties, B8M and B8M Class 2 fasteners provide long-term reliability, reducing maintenance frequency and costs in challenging operational settings.
Materials We Offer
B8M: Standard 316 stainless steel fastener material known for general use in high-corrosion environments.
