| Material | Initial Hardness | Best For |
|---|---|---|
| Mn13 (ASTM A128) | HB 200-230 | General crushing with medium impact |
| Mn13Cr2 | HB 210-240 | Standard jaw plates and cone liners |
| Mn18Cr2 | HB 220-250 | High-impact, abrasive feed |
| Mn22Cr2 | HB 230-260 | Severe impact, hard and large rock |
| High Chrome Cr26 | HRC 58-62 | Blow bars, fine crushing of abrasive material |
* High manganese steel work-hardens under impact to 500+ HB at the wearing surface, giving long life in hard-rock crushing.
