Hammer / Swing Hammer
High-speed swing hammers for Tietjen hammer mills; fine grinding of feed, biomass and grain at 1500-3000 RPM
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Mn13Cr2 | 1.05-1.20 | ≤1.0 | 11.5-14.0 | 1.5-2.5 | — | — |
Excellent work-hardening capability; surface hardness increases under impact, ideal for moderate to high impact crushing conditions
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| AISI 4150H | 0.47-0.54 | 0.15-0.35 | 0.65-1.10 | 0.75-1.20 | 0.15-0.25 | — |
Forged structure with superior fatigue resistance; designed for high-speed hammer crushers with repeated impact cycles (TKK/CoalPactor)
| 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
Grate Bar / Screen
Controls product fineness at mill discharge; slot size determines final particle size distribution
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Cr-Mo Alloy Steel | 0.15-0.25 | 0.30-0.60 | 0.50-0.80 | 1.00-1.50 | 0.45-0.65 | — |
Good combination of hardness and toughness; ideal for SAG mill liners, grate bars and crusher frame liners under abrasive wear
Screen / Sieve Plate
Tietjen mill screen plates; precision-perforated for exact product size control in feed/food processing
| Grade | C | Si | Mn | Cr |
|---|---|---|---|---|
| Mn13Cr2 | 1.05-1.35 | ≤1.0 | 11.0-14.0 | 1.5-2.5 |
Standard work-hardening steel; cost-effective for moderate impact applications
| Grade | C | Si | Mn | Cr | Mo |
|---|---|---|---|---|---|
| AISI 4140 | 0.38-0.43 | 0.15-0.35 | 0.75-1.0 | 0.8-1.1 | 0.15-0.25 |
Forged high-strength steel for shafts, bolts and high-stress components
