Martensitic Stainless Steel Products
Martensitic stainless steel primarily contains 12%-18% chromium and 0.10%-1.0% carbon. Higher carbon content enhances strength, hardness, and wear resistance, while chromium content determines corrosion resistance. It is austenitic at high temperatures and transforms to martensite at room temperature after quenching, offering high strength and hardness. The typical microstructure is martensitic, sometimes with small amounts of austenite, ferrite, or pearlite. It is widely used in high-end kitchenware, tableware, cutlery, brake discs, and razor products.
Currently, JISCO produces martensitic stainless steel compliant with the following standards:
