1.3401 Materiale Piastra in acciaio
1.3401 materiale è un acciaio austenitico ad alto contenuto di manganese with excellent wear resistance and toughness, suitable for high-impact and abrasive applications. It belongs to a broader family of manganese steels including X120Mn12, Mn13, and Hadfield steel, all of which share the key feature of surface work-hardening combined with a tough, nucleo duttile.
- Descrizione
1.3401 is a high manganese austenitic steel widely used for wear-resistant and impact-resistant applications. Its high manganese content stabilizes the austenitic structure, giving it tenacità eccezionale, forte capacità di indurimento del lavoro, and excellent abrasion resistance.
It is commonly used in heavy-duty environments such as mining, cemento, fodere del frantoio, e macchine movimento terra.
Chemical Composition of 1.3401
The chemical composition of 1.3401 is carefully balanced to ensure both 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, improves strength |
| Fosforo (P) | ≤ 0.07 | Controlled impurity |
| Zolfo (S) | ≤ 0.03 | Controlled impurity |
| Cromo (Cr) | ≤ 2.0 | Improves hardness and corrosion resistance |
| Nichel (In) | ≤ 1.0 | Migliora la tenacità |
| Ferro (Fe) | Bilancia | Metallo comune |
Mechanical Properties and Wear Resistance
| Proprietà | Valore tipico |
|---|---|
