The difference between high chromium ball, medium chromium ball and low chromium ball

1) The chromium content of the high chromium ball is required to be between 10% and 30%, and the hardness HRC is ≥58

2) The chromium content of the chromium ball is required to be between 3%-10%, and the hardness HRC is ≥47

3) The chromium content of the low chromium ball is between 1%-3%, and the hardness HRC is ≥45

Under normal circumstances, the higher the chromium content of the steel ball, the higher the hardness, the higher the carbon content, the higher the hardness. Different materials, different working conditions, the material and performance of the steel ball, the requirements are also different.
