Briefing

5155 Oil Hardened and Tempered Spring Steel Wires are mainly used for Suspension Spring,Valve Spring.

Detailed

Products Details

1 High yield ratio, small spring residual deformation.

2 Stable performance: the difference of tensile strength in same coil is less than 60Mpa,which can extend the spring fatigue life.

3 The product rate after winding is high,which can reduce the cost. Oil quenching - tempering spring wire can not completely replace the cold-drawn spring wire. Especially the small size of the spring wire. Oil Hardened and Tempered spring wire is developed for the valve spring, suspension spring in fatigue resistance. And in order to achieve the best results, it should be combined with blasted process after winding. In recent years, with the improvement of the cognition level of this kind of product, this kind of product is gradually applied to clutch spring and car rigging.
