The Oil Tempered and Quenched Spring Steel Wire we made in accordance has some characteristics as follows :
1. High yield ratio, makes sure the remains of spring could hardly deform;
2. Stable performance of the whole wire,the difference of Tensile strength in a same plate is no more than 75MPa,that is convenient for rolling and Improving the fatigue life of it;
3. Compared with the traditional production of spring,it can eliminate some of the processes after wrapping;
4. High success rate of wrapping and less cost.
