Different manufacturing processes

Steel grit is made of carbon steel through high-temperature smelting and spraying, and the manufacturing process is relatively simple. Due to the material, its hardness and life are relatively low, but the price is cheap, suitable for those occasions where surface treatment requirements are not high.

In contrast, steel shot is made of high-quality carbon steel or alloy steel through multiple processes such as continuous rolling and quenching, and the manufacturing process is more complicated. This makes the hardness and life of steel shot higher than steel grit, and it is often used in fields with high requirements for surface finish, such as automobile manufacturing, aircraft manufacturing and optical equipment.

Differences in morphology

Steel grit is polygonal in shape, with large dust, and there are certain hidden dangers to the safety of operators during operation. Steel shot is spherical with a smooth surface, and it causes less damage to the processing equipment during operation.

Difference in hardness

The hardness of steel grit is low, usually between 40-50 degrees. During the manufacturing process, steel shot is heated and quenched to a higher level of hardness, usually between 55-65 degrees.

Different application scenarios

Since steel shot has high hardness and long life, it is often used in fields with high requirements for surface finish. Steel grit is mainly used in casting, forging, steel structure, shipbuilding and bridges.
