Product Introduction

Steel grit is made from high carbon cast steel shot by crushing it into sand grains, and then tempering it into three hardnesses (GH, GL, GP) to suit different needs. The processed steel grit is screened into 10 grades that meet SAE standards to suit sandblasting needs.

Products of different sizes and hardness are used in different situations, such as rod engraving, granite cutting, etc.

Our steel grit adopts the production process of Japan's Shinto Company. The hardness, density and microstructure of the product are very uniform and consistent, and it also has good strength and durability. These characteristics make the product have good cleaning and shot blasting performance.

Steel grit is widely used in the pretreatment of steel workpieces before painting. In this process, the most commonly used method is a sandblasting room with a recycling device. The angular shape of the sand grains and the related hardness make it have a faster cleaning speed and can be effectively recycled.

Steel grit is also widely used in the sand cleaning process of castings. When the workpiece is too hot, sometimes the casting sand will be embedded in the casting, which exceeds the cleaning capacity of the steel shot. At this time, only steel grit can be used.

When the shot blasting equipment using steel shot cannot effectively clean the steel workpiece, steel grit can be used.

Product recommendation

Brown corundum

Brown corundum (aluminum oxide, corundum sand) is suitable for a variety of dry and wet processing processes. It can grind the rough surface of any workpiece finely and is one of the most economical and affordable abrasives. This sharp and angular synthetic abrasive has a hardness second only to diamond and is particularly suitable for use when there are strict requirements for iron contamination. It is used for the roughest cutting and can also be made into a pebble shape to process precision-sized workpieces to achieve extremely low roughness. Due to its high density, sharp, angular structure, it is one of the fastest cutting abrasives currently available.

Steel shot

Steel shot is made of high-quality steel scraps, which are first melted and then shaped into small balls by high-pressure water jets. The formed balls are heated again to purify and homogenize, and then quenched. The quenched balls are dried in a furnace and reheated and tempered to achieve the appropriate hardness. The tempered steel shots are sorted by mechanical screens into 11 grades that meet SAE standards for shot blasting equipment. Products of different particle sizes and hardness are used for different processes, such as surface strengthening.

sodium bicarbonate

Sodium bicarbonate abrasive is a water-soluble green abrasive suitable for open sandblasting with strict requirements for low dust and waste emissions. At the same time, sodium bicarbonate abrasive can also replace traditional chemical paint removers that pollute the environment and be used for the process of removing coatings from delicate workpieces. Sodium bicarbonate abrasive can be used as a dry sandblasting abrasive or when wet blasting with water added to the air flow. In wet blasting cleaning applications, more ideal results can be obtained by adding compounds such as detergents and rust inhibitors. In wet sandblasting, water flow can also play an auxiliary spraying effect. In this way, multiple factors work at the same time, and oil and other debris on the workpiece can be easily cleaned in one blasting process. When used for equipment maintenance purposes, sodium bicarbonate abrasive will not damage seals, bearings, shafts, pumps, etc. At the same time, because it is soluble in water, the workpiece cleaning and dirt emissions can be minimized after sandblasting.
