Performance

42CD4 steel has high hardness and excellent wear resistance and can withstand high-intensity loading and impact forces. The mechanical properties of steel are adjusted through the heat treatment process of normalizing, quenching, and tempering so that the strength, toughness, and plasticity of steel reach an ideal balance. In addition, 42CD4 steel has good machinability and heat treatment properties and can be dyed, passivated, etc. to improve its surface quality and corrosion performance.

Application

42CD4 lost wax investment casting is widely used in the manufacture of machine tools, mechanical equipment, auto parts, ships, aircraft, artillery shells, rockets, and other military equipment, and is also used in the manufacture of accessories in the industrial machinery and aerospace fields. For example, large gears, axles, connecting rods, crankshafts, dead shafts, helical gears, forgings, and other mechanical parts can be made of 42CD4 steel.

To sum up, 42CD4 steel is a kind of lower alloy steel with high strength and good wear resistance. It is widely used in many industrial fields because it can withstand high loads and strong impact forces. It is especially suitable for the manufacture of some mechanical parts that require high strength and wear resistance.
