MCH13A gearbox die casting mould Steel

The materials for gearboxes mainly involve high-strength, high-wear-resistant and high-precision steel materials, especially gear steel, which is one of the core components of AT gearboxes. Gear steel is a special alloy steel, which is widely used in the manufacture of various bearings, gears, transmissions and other machinery, equipment and tools because of its good heat treatment properties, high strength, high toughness and wear resistance. According to different chemical compositions and heat treatment processes, gear steel can be divided into a variety of categories, mainly low alloy hardened and quenched gear steel, high alloy hardened and quenched gear steel, carburised gear steel and spring gear steel. Low alloy hardened gear steel usually contains more chromium, molybdenum, titanium and other elements, with better hardenability and wearability, mainly used in the manufacture of high-load, low-speed, medium-high precision gears and bearings. High alloy hardened and quenched gea…
