ASTM A193 B8M Bolts

ASTM A193 B8 fasteners are a kind of high-performing bolting products made from austenitic stainless steel — Grade 304 (UNS S30400) — primarily for use in applications where standard carbon or alloy steels could not be used due to corrosion or oxidation. The “B8” designation is synonymous with excellent corrosion resistance to atmospheric corrosion, to a wide variety of organic/inorganic chemicals, and to high temperatures. 

The ASTM A193 standard specifically governs the chemical composition of ASME SA193 B8 material such that no unknown elements can be added during manufacturing. This guarantees consistent, predictable performance and superior corrosion resistance across every batch. This reliability makes products like the A193 B8 threaded rod and washer ideal for stabilizing structures in construction, securing equipment in chemical plants, or any application where long-term integrity is paramount.

Understanding the class difference is important for choosing the correct fastener for your operation.

• A 193 B8M Class 1: These fasteners have carbide solution treatment—that is, solution annealed. These processes offer the highest corrosion resistance and ductility, which makes them perfect for uses where environmental durability takes precedence over very high strength.
• A193 B8M Class 2: These fasteners are strain-hardened (cold worked) after the original solution treatment which will give the fastener much higher tensile and yield strength, while still providing excellent corrosion resistance. Class 2 is the class to chose in applications requiring high strength where both mechanical performance and corrosion resistance is required.
