Stainless steel shot is a high-performance metal abrasive made from high-quality stainless steel raw materials through processes such as wire drawing, cutting, and polishing. Qingdao Bairuitong Metal Abrasive Co., Ltd.'s stainless steel shot strictly adheres to the new national standard GB/T 18838.3-2008 and the American SAE standard. The product is spherical in shape, with a dense structure, uniform hardness, no porosity, long service life, and does not damage workpieces. The company's products are manufactured using a passivation method (wire drawing and polishing), achieving sphericity levels of G1, G2, and G3, making the product more durable and effectively improving the matte finish of the workpiece surface.
The company provides stainless steel shot products in the following common materials and grades:
304 material / 430 material / 410 material / 201 material, etc.
Chemical Composition Carbon ≈0.10% Chromium ≈13% Manganese ≈1.2% Specific Gravity Spherical Shot: 7.9g/cm³ Shot: 7.8g/cm³ Hardness 400-600HV Metallographic Structure Martensite Name Stainless Steel Shot Density ≥7.7 Core Advantages
1. Long Lifespan, Low Loss
Stainless steel shot is non-porous and dense, with wear resistance 3-5 times that of ordinary cast steel shot, achieving a cycle life of 5500-12000 cycles. Wear occurs primarily through a layer-by-layer peeling process, reducing dust generation by 90%, minimizing wear on shot blasting equipment, and resulting in lower maintenance costs compared to using high-carbon steel shot.
2. Superior Surface Treatment
After treatment, the workpiece surface is smooth, with thorough removal of oxide scale, achieving a uniform matte metallic finish. It effectively conceals minor defects such as scratches, dents, and mold cracks. It is less prone to rusting or discoloration after treatment, eliminating the need for post-treatment processes such as pickling and cleaning, thus contributing to environmental protection.
3. Environmentally Friendly and Safe
The product does not involve the environmental pollution associated with pickling processes, is less prone to breakage during blasting, and provides a cleaner working environment.
