Mild Steel Shots vs. High Carbon Steel Shots: Characteristics, Applications and Selection Guide

　　Steel shots can effectively remove oxide scale, rust, old paint layers and other impurities on the surface of metal workpieces through shot peening, shot blasting and other processes, providing a clean and uniform base for subsequent processing such as welding, spraying or anti-corrosion treatment. . The use of steel shot for surface cleaning and strengthening during the pretreatment stage can significantly improve the corrosion resistance of metal surfaces. Steel shot peening can introduce surface compressive stress. This "surface hardening" effect can significantly improve the fatigue resistance and overall durability of the workpiece. In addition to improving functionality, steel shot treatment can also give the workpiece a more uniform surface texture. and gloss, whether you are pursuing a matte or moderate finish appearance, it can be achieved by selecting the appropriate steel shot size and shot peening parameters. Compared with traditional chemical treatment methods, steel shot treatment is a more environmentally friendly surface The treatment method produces less waste, is easy to recycle, and reduces environmental pollution. At the same time, the efficient treatment process and the recycling of steel shot also reduce long-term treatment costs to a certain extent. So the steel shot family is divided into two common types: low carbon steel shot and high carbon steel shot. Do you know their differences?

　　Mild steel shot

　　The carbon content is usually 0.08-0.2%. It has good plasticity and toughness and is easy to process and shape.

　　Application areas:

　　Due to its good toughness, it is suitable for surface treatment of precision parts and thin-walled workpieces to reduce the risk of surface damage and is also used to improve surface smoothness and aesthetics.

　　High carbon steel shot

　　The carbon content generally ranges from 0.8% to 1.2%. It has high hardness and strength, but is relatively brittle. Application fields: High carbon steel shot: With its high hardness and wear resistance, it is suitable for heavy industrial fields, such as aerospace, surface strengthening, rust removal and deburring of heavy machinery parts. It can withstand high-intensity operations while maintaining high efficiency. In short, the choice between low carbon steel shot and high carbon steel shot should be based on the specific application scenario, the expected treatment effect and the overall cost-benefit analysis. The correct choice can not only improve work efficiency, but also ensure workpiece quality while optimizing cost expenditures.
