After heat treatment and cold drawing hardening, the strength of 65Mn is higher, and it has a certain degree of toughness and plasticity; under the same surface condition and complete hardening, the fatigue limit is equivalent to that of the alloy spring. However, the hardenability is poor, and it is mainly used for small-sized springs, such as pressure regulating springs, force measuring springs, round and square spiral springs on general machinery, or drawn steel wires as springs on small machinery.
