MCH13A gearbox die casting mould Steel Gearbox materials: mainly high-strength, high-wear-resistant and high-precision steel materials, generally hot-working die steel is selected, especially gear steel, which is one of the core components of AT gearboxes. MCH13A hot-working die steel (also known as: 8418) stainless steel pressure die casting, the main features include: heat resistance, wear resistance, high toughness and tensile strength, and good processing performance, which is very suitable for gearbox materials. Gear steel is a special alloy steel. Due to its good heat treatment performance, high strength, high toughness and good wear resistance, it is widely used in the manufacture of various bearings, gears, gearboxes and other machinery, equipment and tools Gear steel can be divided into many categories according to chemical composition and heat treatment process, mainly low-alloy quenched and tempered gear steel, high-alloy quenched and tempered gear steel, carburized gear s…
