Martensitic stainless steel mainly refers to steel with a chromium content of 12%–18% and a carbon content of 0.10%–1.0%. The higher the carbon content, the higher the strength, hardness, and wear resistance, while the chromium content determines the corrosion resistance of the steel. At high temperatures, it is austenite; after quenching, it becomes martensite at room temperature, featuring high strength and high hardness. The normal microstructure of this type of steel is martensite, and some may also contain a small amount of austenite, ferrite, or pearlite. It is widely used in high-end cookware, tableware, knives and scissors, brake discs, razor products, and other fields.
