Sandblasting treatment has a significant impact on the hardness of stainless steel. Here is a detailed analysis of its impact:
1. Basic functions of Sandblasting processing
Sandblasting treatment is a surface treatment technology that uses high-speed spraying of sand or steel shot and other media to impact and cut the surface of stainless steel to achieve cleaning, removal of oxide layers, and improvement of surface roughness.
2. Effect of Sandblasting Treatment on the Hardness of Stainless Steel
Improved surface hardness: During the Sandblasting process, the high-speed jet of medium impacts and cuts the surface of stainless steel. This effect will form a thick layer of compressive stress on the surface of the material. This compressive stress layer can significantly increase the surface hardness of stainless steel. According to relevant research, the surface hardness of stainless steel treated by Sandblasting can be increased by more than 20%.
Mechanism of hardness improvement: Sandblasting treatment improves the texture of the stainless steel surface and forms a uniform and fine uneven surface. This surface structure helps to store lubricating oil and improve lubrication conditions, thereby further improving the hardness and wear resistance of stainless steel.
Influencing factors: It should be noted that the effect of Sandblasting treatment on the hardness of stainless steel is affected by many factors. First of all, different sandblasting media and treatment processes have different effects on the surface of stainless steel, so it is necessary to select the appropriate sandblasting medium and treatment process according to specific needs. Secondly, the type and original hardness of stainless steel will also affect the effect of Sandblasting treatment. For example, some stainless steel materials with lower hardness may have a more obvious increase in hardness after sandblasting treatment.
In summary, Sandblasting treatment can significantly improve the surface hardness of stainless steel. This improvement not only comes from the compressive stress layer formed on the surface, but also from the improvement of surface texture and lubrication conditions. However, the effect of sandblasting treatment is affected by many factors, so various factors need to be considered comprehensively in practical applications to achieve the best treatment effect.
