High quality NM400 steel for vehicle grade material for sale

The alloying elements of low alloy steel are less than 5%. The low alloy steel is added one or several alloy elements on the basis of carbon steel to improve the performance. Such as manganese, silicon, aluminum, nickel, copper, boron, phosphorus, rare earth, etc. NM400 steel for vehicle Steel with one or more of these elements will have the advantages of high strength and toughness. Due to the addition of few alloy elements, it is called low alloy high strength steel.

20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.

The purpose of NM400 steel for vehicle quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of NM400 steel for vehicle. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
