X120mn12 Acciaio
X120Mn12 steel is a high manganese austenitic steel with superior toughness, resistenza all'abrasione, and work-hardening capability. Compared to Mn12, it delivers enhanced hardness and longer service life in high-impact, high-wear applications, making it an ideal choice for fodere del frantoio, camicie di mulini di macinazione, and heavy-duty wear components.
- Descrizione
X120Mn12 is a high manganese austenitic steel widely used in wear-resistant and high-impact applications. It is characterized by Eccellente tenacia, forte capacità di indurimento del lavoro, and high abrasion resistance.
This material is suitable for mining, fodere del frantoio, mulini macinatori, earth-moving machinery, and other environments where heavy impact and severe wear occur.
Composizione chimica
The typical chemical composition of X120Mn12 ensures a balance between wear resistance and toughness:
| Elemento | Gamma tipica (% in peso) | Funzione |
|---|---|---|
| Carbonio (C) | 1.10 – 1.40 | Increases hardness and surface work-hardening |
| Manganese (Mn) | 11.0 – 14.0 | Stabilizzazione dell'austenite, tenacità, resistenza all'usura |
| Silicio (E) | ≤ 1.0 | Deoxidation and improved strength |
| Fosforo (P) | ≤ 0.07 | Controlled impurity |
| Zolfo (S) | ≤ 0.03 | Controlled impurity |
| Cromo (Cr) | ≤ 2.0 | Migliora la durezza e la resistenza all'usura |

Comparison with Mn12 Steel
| Caratteristica | X120Mn12 | Mn12 |
|---|---|---|
| Carbonio (C) | 1.10 – 1.40% | 0.90 – 1.20% |
| Manganese (Mn) | 11.0 – 14.0% | 11.0 – 13.0% |
| Durezza (soluzione trattata) | 180 – 220 HB | 160 – 200 HB |
| Work-Hardened Hardness | Fino a 500 HB | Fino a 480 HB |
| Robustezza | Alto | Moderare |
| Uso tipico | Fodere del frantoio, mulini macinatori, fodera per secchi | Cade, tramogge, light-impact wear parts |
Riepilogo: X120Mn12 offers higher carbon content and slightly higher manganese, resulting in better work-hardening ability and wear resistance compared to Mn12. While both steels are high manganese austenitic grades, X120Mn12 is generally preferred for heavier impact and extreme abrasion environments.
