ASTM A193 B8 CL3 Fasteners are constructed from austenitic stainless steel, i.e., Type 304, featuring strain-hardened properties to improve strength. The fasteners feature chromium (18%) and nickel (8%), providing superior resistance against corrosion. Mechanically, they have a minimum tensile strength of 125 ksi and yield strength of 100 ksi. The fasteners receive carbide solution treatment and subsequent strain hardening to achieve Class 3 standards. This provides enhanced mechanical properties while maintaining corrosion-resistance qualities, making them suitable for high-stress and high-temperature environments, maintaining structural integrity and longevity in demanding industrial uses.
