Remove oxide skin and sand steel grit g18
Description
Steel Grit is an angular metallic abrasive produced by crushing bearing steel . Steel Grit
is used for descaling, coating and corrosion removal, and surface etching. The angular
particle shape provides a fast cleaning rate and an angular surface profile.
All our bearing steel grit are made of chrome alloy materials.(cast steel grit contains no chrome element)
After heat treatment ,it is featured with optimum mechanical characteristics,good tenacity,high fatigue
resistance,long working-life,low consumption.It is widely used in sand blasting for surface preparation before
coating.And it have 30% saved.
