1: 65Mn steel introduction
65Mn steel is a Chinese GB standard spring steel grade. Its strength, hardness, elasticity and hardenability are higher than that of 65# steel, but it has superheat sensitivity, easy to produce quench crack and temper brittleness. The annealed state has good machinability, and the cold deformation plasticity is low, but the weldability is poor.
