Sunwill supply Manganese steel blow bars and with TIC carbide inserts. Manganese steel blow bars have the best impact resistance but the wear resistance is the lowest at the same time. It is usually used in the primary crushing.
With the TIC carbide inserts on the wear face, working life of the Manganese steel blow bars can be largely increased.
Below is the selection guidance of blow bars for different applications:
| Code | Material | Basis Hardness | Wear Resistance | Applications |
| 200S | Manganese steel | 200-250HB | Relatively low | Large feed size low-abrasiveness stones,e.g. limestones. |
| 200ST | Manganese+Tic | 200-250HB | Up to 100% increased than Manganese | Same as above but where longer wear life required. |
| 550M | Martensitic Steel | 500-580HB | Medium | Medium feed size of low to medium abrasiveness, such as Limestones, Asphalt, Concretes, Building rubbles with steel rebars or a small quantity of unbreakable objects. |
| 550MC | Martensitic +Ceramic | 500-580HB | Up to 100% increased than Martensitic | Same as above but where longer wear life required. |
| 650C | Chrome casting | 650-700HB | High | Small feed size of medium to high abrasiveness but low strength, such as Limestones, Asphalt, Concretes, Building rubbles without steel rebars or unbreakable objects. |
| 650CC | Chrome +Ceramic | 650-700HB | Up to 100% increased than Chrome | Same as above but where longer wear life required. |
| 700CX | Chrome +Ceramic | 700+HB | Up to 200% increased than chrome | Small feed size of high abrasiveness and high strength materials, such as gravels, granites without unbreakable objects |
