After heat treatment and cold drawing hardening, the strength is relatively high, with a certain degree of flexibility and plasticity; Under the same surface condition and complete quenching, the fatigue limit is equivalent to that of a multicolored alloy spring. However, the hardenability is very poor, and it is mainly used for springs of smaller sizes, such as pressure regulating and speed regulating springs, force measuring springs, circular and square spiral springs in general machinery, or springs drawn into steel wires for small machinery.
