65Mn is spring steel, Mn improves hardenability,65Mn surface decarburization is tendency than silicon steel, after the heat treatment better than the overall mechanical properties of carbon steel, but the thermal sensitivity and temper brittleness.
65Mn can also be used to make spring ring, valve spring, clutch reed, brake spring and cold-drawn coil cold coil coil spring for small size, flat spring, cushion spring, spring spring.
