Alloy steel shot S390 has high hardness and good performance, making it an ideal product for shot blasting. Alloy steel balls are made from scrap steel. The scrap steel is melted first, and then the molten steel is made into small balls using high-pressure water.
I believe that through the previous content introduction, everyone should have a certain understanding of alloy steel shot, knowing that this product has been widely used in the casting industry with its own advantages, and can help workpieces remove surface sand particles through shot blasting. But if the shot blasting effect is ideal, there are many conditions involved, and the quality of the product also affects the shot blasting effect of the workpiece. What is the impact of product quality on shot peening effect? Let's discover together.
The influence of alloy steel shot on the surface roughness of materials is usually within the range of Ra0.6~20mm. Without changing the process parameters, the higher the original surface roughness of the material, the greater the Ra value after shot peening. Practice has shown that in general, if the surface roughness before shot peening is below 6.3 millimeters, shot peening can improve or maintain the original surface roughness; If the original surface roughness is above 6.3 millimeters, the surface roughness after shot peening will decrease.
2. Alloy steel balls of different specifications have different hardness, but products with different hardness have different cleaning effects on workpieces. The greater the hardness, the greater the brittleness. When cleaning workpieces, although the cleaning efficiency is greatly improved, the consumption of steel balls will also increase. At the same time, the service life of the steel shot will also be shortened. Therefore, from the perspective of economic benefits, we recommend using steel balls with moderate hardness for rust removal of general workpieces.
The processing effect of the workpiece is not only related to the alloy steel shot and hardness, but also to its model and shape. For example, products with irregular surfaces have higher rust removal efficiency than products with circular surfaces, but the surface is rough. So when consumers choose steel shot rust removal, they must start with the model, hardness, specifications, and shape of the steel shot according to their actual needs.
4. Product strengthening shot blasting can cause plastic deformation of the sprayed surface of the parts, thereby changing the surface roughness of the parts. Surface roughness is a type of micro geometric error, also known as micro roughness. Surface roughness, like surface roughness and shape error, belongs to the geometric shape error of parts, and surface roughness has a significant impact on the performance of mechanical parts.
Due to its bright appearance and non rusting properties, alloy steel shot is widely used for surface spraying and polishing treatment of high hardness workpieces such as automotive springs, suspension springs, quenched gears, screws, chains, various stamped parts, standard parts, and stainless steel. It has the functions of surface peeling and surface strengthening treatment for processed workpieces.
