Alloy Steel F11 Bars and Rods are mainly made up of chromium (1–1.5%), molybdenum (0.44–0.65%), along with controlled amounts of carbon, manganese, silicon, phosphorus, and sulfur. This alloy is known for its impressive creep resistance, thermal stability, and toughness even at elevated temperatures. With a tensile strength of about 415 MPa and a yield strength of 205 MPa, it boasts excellent ductility and machinability. Its hardness and impact resistance make it ideal for pressure-containing components. The blend of chromium and molybdenum not only enhances corrosion resistance but also boosts strength, ensuring reliable performance in both high-temperature and high-pressure settings.
