ASTM A193 B8T Nuts mainly consist of chromium (17–19%), nickel (9–12%), and titanium (0.4–0.7%), along with trace amounts of carbon, manganese, silicon, phosphorus, and sulfur, with iron making up the rest. The addition of titanium stabilizes the structure, preventing carbide precipitation and boosting resistance to intergranular corrosion. These nuts boast a tensile strength of around 515 MPa and a yield strength of 205 MPa, ensuring remarkable toughness and creep resistance. Their high levels of chromium and nickel offer excellent oxidation resistance up to 870°C (1600°F), making them reliable for high-temperature and high-pressure applications in aggressive environments.
