Alloy Steel F11 is generally composed of about 1.25% chromium and 0.5% molybdenum, in addition to trace amounts of carbon, manganese, phosphorus, sulfur, and silicon. It has a minimum yield strength of 205 MPa and tensile strength between 415-585 MPa with excellent ductility and elongation of more than 20%. Chromium enhances resistance to oxidation at high temperatures, while molybdenum increases strength and corrosion and creep resistance. The material can be heat-treated and shows stability and performance in usage subject to thermal cycling and high mechanical stress.
