Product: Bearing steel grit
We have two kind steel grit(bearing steel grit and cast steel grit)
Bearing steel Grits
Bearing steel grits are produced by bearing steel grit after heat treatment. Steel grits have
high resistance and is a kind of hard product preferred for many surface operations. Steel grits
has been divided into three groups of different hardness according to their intended purpose.
Hardness selection
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: >60HRC
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.
