The grate plate used for grate cooler is very important castings for cement production. The casting quality have big influence on machine performance, thus will have big influence on cement quality. The casting work under high temperature, with wear resistant requirement, so we choose Cr25Ni20 as most suitable material. We also produce according to material requriement from customer if there have any special requirement by user.
Material requirement as follow:
| C% | Mn% | Si% | P% | S% | Cr% | Ni% | Mo% |
| 0.3-0.45 | 1-1.5 | 1.0-2.0 | ≤0.03 | ≤0.03 | 24-26 | 19-21 | 0.4-0.6 |
| σb (MPa) | σ0.2 (MPa) | δ5 (%) | ψ (%) | HBW |
| ≥515 | ≥205 | ≥35 | ≥50 | ≤182 |
