High Chrome vs Martensitic vs Mn+TiC vs MMC — A Practical Comparison
Use this quick reference to align alloy families with real-world duties in recycling, quarry, and cement.
Impact tolerance vs abrasion resistance
Manganese maximizes shock tolerance; martensitic balances shock and abrasion; high chrome is for clean, abrasive, low-shock duty. TiC or ceramic reinforcement preserves the strike edge where shocks are controlled.
Rule-of-thumb envelopes
| Duty | Primary Choice | Upgrade Path |
|---|---|---|
| Primary, unknowns | Mn | Mn + TiC if edges round fast |
| Recycling, screened | Martensitic | Martensitic + Ceramic |
| Clean secondary | High Chrome | Hi-Cr + Ceramic → Ceramic-reinforced |
