Supreme Steels

36XHTO

Product Description:

36XHТO is a low-alloy steel primarily designed for high-strength applications with good wear resistance and moderate corrosion resistance. Its chromium and nickel content provide a balance of mechanical properties, making it suitable for demanding industrial environments. This is an alloy steel grade that combines strength, toughness, and wear resistance with moderate corrosion resistance. It is commonly used in the aerospace, automotive, and heavy machinery industries, particularly for components subjected to dynamic loads.
