High Strength 65mn Steel Round Bars Stockists - China

After heat treatment and cold drawing hardening, the strength is relatively high, and it has certain flexibility and plasticity; under the same surface state and complete hardening, the fatigue limit is equivalent to that of the colorful alloy spring.

However, the hardenability is very poor, and it is mainly used for smaller-sized springs, such as pressure-regulating speed-regulating springs, force-measuring springs, round and square coil springs on general machinery, or drawn steel wires as springs on small machinery.
