Ship hull rust removing used abrasive grit gh40
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.

Hardness
GP Steel Grits
Hardness: 40 - 50 HRC
They have sharp and angular structure and a kind of material that generally used for the cleaning purposes.
According to GL and GH quality products, GP steel grits are softer than GL and GH qualities and have been
lost their sharpness and angular structure by abrading in short period during usage.
GL Steel Grits
Hardness: 53 - 60 HRC
They are much harder products than GP and have sharp and angular structure. During blasting, if even not quickly
as GP, they lose their sharpness and angular features gradually. Generally are used in painting, operations before
coating and surface preparation.
GH Steel Grits
Hardness: 60 - 68 HRC
They are kind of product that has maximum hardness among steel grits. They have sharp and angular structure and
they are not lost their sharp and angular features during operations. They are used surface cleaning of high hardness
products and surface roughening operations effectively. Provides homogenous surface appearance. GH steel grits are
used in granite cutting operations.
