| Element | Specification | Function |
|---|---|---|
| High-Carbon Cast / Tempered Steel Grit | ||
| C — Carbon | 0.80–1.20% | Provides hardness, cutting power, and wear resistance. |
| Mn — Manganese | 0.60–1.20% | Improves toughness, impact strength, and abrasive durability. |
| Si — Silicon | ≥ 0.40% | Supports strength and helps improve deoxidation control. |
| S — Sulfur | ≤ 0.05% | Controlled impurity to maintain abrasive quality. |
| P — Phosphorus | ≤ 0.05% | Controlled impurity to reduce brittleness risk. |
| Fe — Iron | Balance | Base material of high-carbon cast steel grit. |
Note:
This chemical composition applies to both cast steel grit and tempered steel grit.
GP, GL, and GH are hardness grades, not separate chemical systems. Final composition can be verified by batch COA.
