ASTM A193 B8T Bolts are constructed from Type 321 stainless steel, which is stabilized with titanium to prevent intergranular corrosion and maintain strength even at high temperatures. This alloy typically includes chromium (17–19%), nickel (9–12%), and at least 0.35% titanium. With a minimum tensile strength of 515 MPa and a yield strength of 205 MPa, these bolts also offer good elongation and hardness. They excel in oxidation resistance, high creep strength, and perform exceptionally well in both acidic and high-temperature environments, making them perfect for applications that involve continuous heat exposure and corrosive substances.
