Of course chromium cast balls undergo lower wear rates. As the chromium content increases, wear rate will be reduced. Experience with our grinding balls shows that mediumchromium cast grinding balls (712% Cr) will have around 10% lower wear rate compared to 70Cr2 forged grinding balls of the same size that enjoy a small chromium content.
