Heat treatment of steel 65 mn

Heat treatment of steel belt mn spring steel, believes that many and steel with the contact person should were familiar with this name. In the production of metal and equipment manufacturing industries can be used in it. Mn, Mn improve hardenability, phi mm steel oil can be hardening, surface decarburization tend to be smaller than silicon steel, after heat treatment of the comprehensive mechanical performance is better than that of carbon steel, but there are overheating sensitivity and temper brittleness. Used for small size flat, round spring, seat cushion, spring, spring wind, also can make the spring ring, brake valve spring, spring and cold drawn steel cold roll coil spring. In mn steel belt heat treatment is more rich content of manganese and manganese can improve the hardenability, phi mm steel oil can be hardening, surface decarburization tend to be smaller than silicon steel, after heat treatment of the comprehensive mechanical performance is better than that of carbon steel, but there are overheating sensitivity and temper brittleness. Used for small size flat, round spring, seat cushion, spring, spring wind, also can make the spring ring, brake valve spring, spring and cold drawn steel cold roll coil spring. Mn steel heat treatment at the same time with excellent comprehensive performance, such as mechanical performance, Especially the elastic limit, ultimate strength, showed) , annor reduction performance ( The elasticity decreased resistance, also called relaxation resistance) , fatigue performance, hardenability, physical and chemical properties ( Heat resistant, good low temperature resistance, oxidation resistance, corrosion resistance, etc. ) 。 In order to meet the performance requirements, spring steel has good metallurgical quality ( High degree of purity and uniformity) , good surface quality, Strictly control the surface defect and decarburization) , accurate shape and size.
