Dalian Yuquan Metal Products Co., Ltd.

Bearing steel known as good abrasion resistance, high hardness, is a special kind of metal materials, including chromium is a formation of carbide alloy elements, chromium can significantly change the state of the particle size and distribution of carbide in steel.When annealing of chromium carbide chromium carbide refining, and have played an important role in refining grain size.This organization after quenching and low temperature tempering, the bearing steel has good wear resistance, hardness, strength, elastic limit and increase the stability of austenite in steel, improve the hardenability of steel. So made of bearing steel alloy steel shot, no matter from the chemical composition, scientific and reasonable heat treatment process, to ensure that it has enough hardness and toughness, these excellent features, is unmatched by ordinary cast steel shot, belong to high quality abrasive products. Effectively reduce the coating abrasive attrition rate: bearing alloy steel grit as raw material is made of high quality bearing, because contain precious metals - chromium (Cr) element, enhance the fatigue life of the product itself and wear-resisting degree, so the coating on the use of bearing alloy steel grit can effectively improve the utilization rate of recycling lower abrasive wear and tear.By repeated data obtained from field at present, all can lower than 0.2 kg / ㎡ loss requirement, surface treatment effect ISO8501-94: in the standard level of derusting SA2.5.
