Low chromium balls
Date：2023-08-06 Views:
Low chromium balls are also commonly used steel balls, and are mostly used in industries that do not require very high wear-resistant materials, because their chromium content is higher than that of low chromium balls, so they have higher hardness and higher wear resistance. In terms of high cost performance.
