The chrome content with the relationship as-cast hardness and quenching hardness

The chrome content with the relationship as-cast hardness and quenching hardness.

In theory, with the increase of chromium content, the number of carbides in the steel ball will increase, and the hardness of the steel ball as cast and quenching will continue to increase.

When the chromium content reaches about 16%, the cast hardness and quenching hardness of the steel ball reach the peak. When the chromium content reaches more than 21%, the cast hardness and quenching hardness of the steel ball begin to slowly decline. When the chromium content reaches more than 30%, the cast hardness and quenching hardness of the steel ball are getting lower and lower, and sometimes the steel ball will crack when it is cast. 

Therefore, the higher the chromium content of the high-chromium casting ball, the hardness of the steel ball as cast and quenching hardness will not be higher and higher. If you want to know about steel ball knowledge and grinding knowledge, welcome to contact with Dexin
