... (personal communication) Figure 7.11 shows how a class 30 gray cast iron compares to some other metals in two-body abrasion resistance. The relatively soft gray iron has abrasion resistance better than low-carbon steel at about the same hardness, but it is not as abrasion resistant as a common tool...

... has the advantage of lower alloy cost, and, more important, provides a 15 to 30% improvement in life. All grinding balls require tempering for 8 h at 260 to 315 °C (500 to 600 °F) to develop adequate impact toughness. The high-chromium class II and III white irons have excellent abrasion resistance...
