STEEL GRIT
1. Introduction
Steel grit is a cast austenitic steel spherical abrasive. Steel Shot is used for surface finishing, cleaning, descaling, deburring, casting sand removal, coating removal and surface preparation. Steel Grit is used for industrial foundry, forging plant, heat treatment shop, steel construction plant, container manufacturer, ship builder, auto and locomotive manufacturer

3.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 beenlost 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 structur
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.
