ASTM A193 B8C Stud Bolts are crafted from AISI 347 austenitic stainless steel, featuring carefully controlled amounts of chromium, nickel, manganese, and other elements to enhance corrosion resistance and strength. The material undergoes carbide solution treatment and can be further strain-hardened to boost mechanical performance. B8C grades are known for their high tensile strength and yield properties, making them suitable for high-temperature and high-pressure environments. Typical mechanical characteristics include a minimum tensile strength of around 125 ksi and a yield strength exceeding 100 ksi in smaller diameters, along with robust elongation and hardness requirements that ensure reliable and durable bolting performance.
