55CrSi YB /T 5105-1993 oil quenched steel wire, after oil quenching and tempering treatment, this steel wire obtains excellent physical and chemical properties. Oil quenching treatment can quickly cool the steel wire, so that it can obtain high hardness and strength, and tempering treatment can eliminate the internal stress generated during quenching process, improve the toughness and fatigue strength of the steel wire.

55CrSi YB /T 5105-1993 oil quenched steel wire performance feature：

1. High strength and high elasticity: 55CrSi oil-quenched steel wire has high yield strength and tensile strength, while maintaining good elasticity. This allows it to maintain a stable shape and performance when subjected to high or alternating stresses.

2. Good fatigue strength: due to the special heat treatment process, this steel wire has excellent fatigue strength and can maintain stable performance under long-term alternating stress.

3. Good creep and relaxation resistance: under high temperature or high stress environment, 55CrSi oil-quenched steel wire can maintain sufficient elasticity and stability, and is not easy to creep and relaxation.

4. Excellent corrosion resistance: Spring steel wire used in specific environments, such as corrosive media, 55CrSi oil-quenched steel wire can show good corrosion resistance.
