1.3401 Material Steel Plate
1.3401 material is a high manganese austenitic steel 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, ductile core.
- Description
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 exceptional toughness, strong work-hardening ability, and excellent abrasion resistance.
It is commonly used in heavy-duty environments such as mining, cement, crusher liners, and earth-moving machinery.
Chemical Composition of 1.3401
The chemical composition of 1.3401 is carefully balanced to ensure both wear resistance and toughness:
| Element | Typical Range (wt%) | Function |
|---|---|---|
| Carbon (C) | 1.10 – 1.40 | Increases hardness and surface work-hardening |
| Manganese (Mn) | 11.0 – 14.0 | Austenite stabilization, toughness, wear resistance |
| Silicon (Si) | ≤ 1.0 | Deoxidation, improves strength |
| Phosphorus (P) | ≤ 0.07 | Controlled impurity |
| Sulfur (S) | ≤ 0.03 | Controlled impurity |
| Chromium (Cr) | ≤ 2.0 | Improves hardness and corrosion resistance |
| Nickel (Ni) | ≤ 1.0 | Enhances toughness |
| Iron (Fe) | Balance | Base metal |
Mechanical Properties and Wear Resistance
| Property | Typical Value |
|---|---|
| Yield Strength | 350 – 450 MPa |
| Tensile Strength | 750 – 1100 MPa |
| Elongation | ≥ 35% |
