|---|---|---|---|
| WC-Co Cemented Carbide | 84-89% | 11-16% | ≤1% |
Extreme hardness for HPGR roller studs and VSI rotor tips; 5-10x longer life than Cr26 in pure abrasion; requires careful installation to avoid thermal shock
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Cr26 | 2.0-3.3 | ≤1.0 | 0.5-1.5 | 23.0-30.0 | 1.0-3.0 | ≤1.5 |
Excellent abrasion resistance with M7C3 carbide network; 3-5x longer life than Mn steel in pure abrasive wear; ideal for vertical mill rollers and VSI rotors
SBM VSI anvil plates for rock-on-steel crushing; available in Cr26 for maximum abrasive resistance
| Grade | C | Si | Mn | Cr | Mo |
|---|---|---|---|---|---|
| Cr20 | 2.0-3.3 | ≤1.2 | ≤1.5 | 18.0-23.0 | ≤3.0 |
High hardness with moderate toughness; excellent for impact-crusher blow bars and hammer tips
| Grade | C | Si | Mn | Cr | Mo |
|---|---|---|---|---|---|
| Cr26 | 2.0-3.3 | ≤1.2 | ≤1.5 | 23.0-30.0 | ≤2.0 |
Highest hardness for abrasive wear; best for fine crushing and grinding applications with low impact
