steel grit

Cast steel grit is commonly called steel grit, arc steel grit and angular steel grit, which are the upgrade substitutes for cast iron grit and iron grit, and are used as the metal abrasive in shot blasting machines, shot blasting equipment, shot blasting cleaners, shot blasting machinery, shot peening machines, shot peening equipment, sand blasting machines, sand blasting equipment, steel pretreatment product lines, steel plate pretreatment product lines, steel structure pretreatment product lines. This product adopts the raw materials which are carefully selected, and are added with the alloys with the best proportion, and are transformed into steel grains after electric furnace smelting. In the process of the liquid metal forming steel grains, its chemical composition and granularity are strictly controlled, in order to guarantee that its mechanical characteristics conform to various usages. After high temperature process, the steel grains break into steel grit which is classified into various specifications of grit by the automatic screen classification system.

The hardness degree of GL steel grit is higher than the GP steel grit, but their edge angles are rounded when sand blasting operation, so they are especially suitable for the pretreatment operation of steel surface oxide skin removing. The hardness degree of GH steel grit is very high, and it maintains edge angles when sand blasting operation, so its especially effective to forming the regular and hair-like surface. This kind of steel grit is mainly used in compressed air shot blasting equipment.
