G18 G25 G30 Bearing Steel Grit for Granite Gang Saw
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:
- 1. Made by crushing the Chromium bearing steel without any casting defects
2. The sharp edges have higher mechanical property and good harden ability than usual cast steel grit
3. Better used for Granite cutting
Bearing steel grit is made of chrome alloy material which are fast atomized after melting.After heat treatment,it is featured with optimum mechanical characteristics, good tenacity,high fatigue resistance,long working-life,low consumption and so on. 30% will be saved. Mainly used in granite cutting,sandblasting and shot peening.
