However, it is possible to strain to harden this material to approximately 500 HB by subjecting it to high-impact loading while limiting gouging abrasion. In crushing applications, where the main wear mechanism is gouging abrasion, the manganese steel will usually harden to some intermediate level, typically between 350-450 HB.

High Cr cast irons are alloys based on the Fe–Cr–C system, usually in the range from 10 to 30% Cr and from 1.8 to 4% C. Commercial alloys contain up to 1% residual Si and additions of Mn, Mo, Ni and Cu to increase hardenability. In this range of compositions most of the alloys solidify as mixtures of austenite and M 7 C 3 carbides [1].
