Steel wire grinding shot (also known as high-manganese steel shot/grinding shot) is an upgraded replacement for steel wire cutting shot. Bairentong uses high-quality high-carbon steel wire (45#/50#/60#/70#/80#) as raw material, refined through three core processes: wire drawing, precision cutting, and chamfering rounding.
Compared to the shortcomings of traditional cast steel shot (fragile and dusty) and ordinary cutting shot (which leaves sharp edges that damage workpieces), Bairentong grinding shot combines the dual advantages of high wear resistance and low roughness, making it an ideal metal abrasive for workpiece surface strengthening, cleaning, and shot blasting.
Core Processes
Pure Material: Utilizing high-carbon/high-manganese raw materials, it is internally dense and absolutely free of pores and cracks.
Uniform Particle Size: High screening precision and strict control of the length-to-diameter ratio ensure uniform impact force.
Excellent Metallographic Structure: The metallographic structure is tempered martensite/troostite, guaranteeing optimal toughness.

Product Advantages
1. Extended Service Life, Reduced Overall Costs
Baitong grinding steel shot has no casting defects, excellent toughness, and a cycle life more than 3 times that of ordinary cast steel shot. Its consumption follows a gradual wear process from large to small particles, until the particles shrink to 3/10 of their original volume before being removed by the dust extraction system, eliminating ineffective dust and saving equipment maintenance costs.
2. Superior Shot Blasting Effect: No Damage to Workpieces, and Surface Strengthening
For precision parts: Ordinary sharp-edged cutting shot will scratch the workpiece surface, leaving dents. Our grinding steel shot, with its rounded bevel, can remove oxide scale and burrs while reducing the surface roughness (Ra value) of the workpiece.
For high-strength parts: It can effectively generate compressive stress, significantly improving the fatigue life of components such as springs and gears.
3. Environmental Protection and Efficiency
Dust production is reduced by 30%-50% compared to cast steel shot, improving the workshop working environment and reducing the burden on the dust collection system. At the same time, the cleaned workpiece directly exhibits a uniform matte metallic finish, eliminating the need for secondary treatments such as acid pickling. Main Application Areas
Baitong steel wire grinding shot is specifically designed for industries with high requirements for workpiece surface quality and strengthening:
