Martensite stainless steel is a kind of stainless ones with martensite microstructure.The amount of "chrome" in the steel is attribute to corrosion resistance, and the range is from 11.5 to 18%, the higher the chromium content of the steel, the higher carbon content required in the process of heat treatment. Martensitic stainless steel has high strength, but poor ductility and weldability. And martensitic stainless steel 1Cr13, 3Cr13 are commonly used grades, due to high amount of carbon, it has high strength, hardness and wear resistance, with a litter low corrosion resistance. Martensite stainless steel can be used on parts with the requirements of high mechanical performance and general corrosion resistance.
