Mantles, Concaves, Feed cones
Primary crushing surface for UZTM (УЗТМ) KKD series gyratory crushers; Russian-standard primary crushing for iron ore and non-ferrous mining
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Mn18Cr2 | 1.05-1.35 | ≤1.0 | 16.0-19.0 | 1.5-2.5 | — | — |
Higher Mn content provides superior work-hardening depth; 20-30% longer service life than Mn13 in high-compression applications
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Mn13Cr2 | 1.05-1.20 | ≤1.0 | 11.5-14.0 | 1.5-2.5 | — | — |
Excellent work-hardening capability; surface hardness increases under impact, ideal for moderate to high impact crushing conditions
Stationary crushing ring for KKD crushers; GOST-standard manganese steel; segmented for maintenance efficiency
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Mn18Cr2 | 1.05-1.35 | ≤1.0 | 16.0-19.0 | 1.5-2.5 | — | — |
Higher Mn content provides superior work-hardening depth; 20-30% longer service life than Mn13 in high-compression applications
KKD gyratory concave segments; Mn22Cr2Mo option for Russian mega-mine primary crushing duty
| Grade | C | Si | Mn | Cr |
|---|---|---|---|---|
| Mn18Cr2 | 1.05-1.35 | ≤1.0 | 16.0-19.0 | 1.5-2.5 |
Superior work-hardening depth; 20-30% longer life than Mn13 in high-compression applications
| Grade | C | Si | Mn | Cr | Mo |
|---|---|---|---|---|---|
| Mn22Cr2Mo | 1.10-1.40 | ≤0.8 | 20.0-24.0 | 1.8-2.5 | 0.3-0.6 |
Maximum work-hardening capability; best for severe impact and high-compression crushing; 40-60% longer life than Mn13
