Bearing alloy steel grit made from forged bearing steel off cuttings

Product Overview

Description

Bearing Steel Grit is made by crushing forged bearing steel. It is initially developed and used for the stone sawing industry and now also well accepted for the blasting process due to its high performance. Compared with traditional steel grit made by crushing steel shot,bearing steel grit has the following features:

 

Raw Material

Bearing steel grit is made by Chromium bearing steel which has good harden ability due to its high content of Chromium.

Technology

Bearing steel grit is made by crushing the forged bearing steel directly which is free from casting defects.

Low wear

The forged state bearing steel grit with sharp edges has higher mechanical property than traditional cast steel grit with ball surfaces.
