Steel grit is divided into GP steel grit, GL steel grit and GH steel grit according to the hardness. Different models have different application ranges. Let Songhuai Steel Shot explain to you the specific performance and use time of various types of steel grit. Matters needing attention and the relationship between hardness and service life.
Among them, GP steel grit is a new product in the abrasive industry at present. Generally, it is produced in a sharp-edged shape, but in the practical process, its edges and corners will be rounded soon, so this product is only suitable for Pretreatment for descaling of steel surfaces.
Although the hardness of GL steel grit is slightly higher than that of GP steel grit, the edges and corners will be rounded soon, so it is only suitable for the pretreatment of descaling on the surface of steel.
GH steel grit is the hardest of the three types and will maintain its edges and corners during blasting operations, making it especially effective on regular and hairy surfaces. Mainly used in shot peening equipment for compressed air.
So is the stronger the hardness of the steel grit, the better? The answer is no, the hardness of the steel grit is directly proportional to the consumption. People who are engaged in the related abrasive industry should understand this. The harder the steel grit is, the faster the workpiece will be cleaned, but the consumption will be higher. quick.
The hardness of the steel grit is directly proportional to the consumption. People in the abrasive industry know that when the hardness of the steel grit is greater, the speed of cleaning the workpiece will be very fast, but the corresponding consumption of the steel grit will also become very fast. Then its service life will be shortened faster than normal time. Therefore, generally from the perspective of economic benefits, generally
Before the workpiece is cleaned, steel grit with moderate hardness will be selected for processing.
As a metal abrasive, steel grit is mainly used in the shot peening of large quantities and heavy parts or materials in machinery, aviation, casting, etc., and the descaling and rust removal of steel workpieces before coating. Steel grit has moderate hardness, strong toughness, impact resistance, relatively long service life, and relatively fast cleaning speed. The important point is that it can be used repeatedly. In recent years, there has been a growing demand in the market. trend. Therefore, the use of steel grit should be selected according to the material and hardness of the workpiece, so as to improve the service life of steel grit.
