Alloy Steel F91 is a specialized chromium-molybdenum-vanadium (Cr-Mo-V) tempered martensitic steel, crafted with precise levels of carbon, manganese, and other alloying elements. This unique blend gives it remarkable creep strength, oxidation resistance, and durability at high temperatures. When it comes to mechanics, F91 bars and rods boast incredibly high tensile and yield strength, along with good toughness and excellent fatigue resistance. Typically, the tensile strength falls between 800 to 900 MPa, while the yield strength hovers around 600 to 650 MPa, depending on the heat treatment and tempering processes used.
