SUS440A stainless steel is a high-carbon, high-chromium martensitic stainless steel designed to provide stainless properties with superior hardness. The alloy offers a superior combination of superior strength, ductility, toughness, corrosion resistance and machinability. After heat treatment, its hardness can reach Rockwell C56, and it retains good toughness at low temperatures, and has relatively high tensile strength and yield strength at medium and high temperatures. These properties further increase the versatility and practicality of the alloy.
