Oil tempered spring steel wire

We are oil tempered spring steel wire manufacturer, the material has high strength, elastic limit, yield ratio, hardenability and temper resistance stability, very wide use, mostly used in some important springs and wear serious wear under fatigue performance in higher stress, such as spring ring, shock absorber spring and brake spring, automobile, locomotive, tractor coil spring, Cylinder safety valve spring and some mechanical wear bar, etc.

Introduction to Materials

Steel wire grades 65Mn, 60Si2MnA, the material has high strength, elastic limit, yield ratio, hardenability and temper resistance stability, very wide use, mostly used in some important springs and wear serious wear under fatigue performance in higher stress, such as spring ring, shock absorber spring and brake spring, automobile, locomotive, tractor coil spring, Cylinder safety valve spring and some mechanical wear bar, etc.
