Products Description
X120Mn12 is a high manganese grade steel that offers excellent wear resistance, high strength, and good toughness. This steel is widely used in mining, construction, manufacturing, and other industries due to its unique properties.
Properties:
• High wear resistance
• High strength
• Good toughness
• Good ductility
• Good machinability
• Good weldability
• Good corrosion resistance
Chemical Composition:
• Carbon: 1.10%-1.30%
• Manganese: 11.00%-14.00%
• Silicon: 0.60% max
• Phosphorus: 0.040% max
• Sulfur: 0.050% max
X120Mn12 steel is a popular choice for wear applications because of its excellent properties. The high manganese content in the steel increases its toughness and wear resistance. Additionally, the steel's good ductility, weldability, and machinability make it easy to work with.
This steel is also resistant to corrosion, further increasing its longevity. However, it is important to note that X120Mn12 steel is not suitable for use in environments where the operating temperatures regularly exceed 250°C.

FAQ
Q: Can I flame cut X120Mn12 steel plate?
A: No, you must never use a flame torch. The intense heat will cause severe hardening and micro-cracking on the cut edge, which will lead to catastrophic failure in service. Use waterjet, plasma, or abrasive saw cutting instead.
Q: Why is X120Mn12 (Mn13) so difficult to drill?
A: Because it work-hardens rapidly. The moment the drill bit touches the surface, the steel hardens to over 300 HB. You must use high-rigidity machines, carbide tooling, and constant high feed rates to cut under the hardened layer.
Q: The plate is only 200 HB initially. How can it be wear-resistant?
A: Its wear resistance comes from impact hardening. When subjected to heavy blows or high pressure, the surface layer instantly hardens to >300 HB. The harder the impact, the more wear-resistant it becomes, which is why it is used in crushers and excavators.
Q: How do I weld X120Mn12 if it cracks?
A: You must use austenitic stainless steel electrodes (like E308) and keep the heat input very low. Do not preheat. Weld in short, intermittent passes and cool the part immediately between passes to avoid overheating the base metal.
Q: What are your standard stock sizes for this plate?
A: We keep regular stock in our warehouse, usually in widths of 2000mm and lengths of 6000mm. Standard thicknesses include 6mm, 8mm, 10mm, 12mm, and 20mm. Custom sizes can be rolled at our base.
