Tavole e fogli di manganese di grado x120mn12

X120mn12 acciaio di manganese, Conosciuto anche come acciaio di manganese duro, è rinomato per le sue proprietà uniche. Diventa significativamente più duro e più resistente all'usura attraverso un'intensa lavorazione a freddo pur mantenendo un'elevata durabilità.

Caratteristiche principali

Strength and Hardness
- In its quenched state, manganese steel enhances its low initial tensile strength and hardness through cold working.
- The cold-worked layer becomes highly wear-resistant without compromising durability.
Versatilità
- Il materiale può essere piegato, flangiato, and pierced due to its excellent flexibility.
- Chipping at room temperature is possible but limited, requiring hard metal tools.

Applicazioni tipiche

Manganese steel is ideal for parts exposed to heavy percussion and impact stresses, compreso:

Hangers in blasting machines
Crusher jaws and inserts
Power shovel bolts and connectors
Gripping teeth
Impact and centrifugal mills
Protective grills, rivestimento, doors, and safety plates

Welding Properties

Welding Methods
- Manganese steel can be welded electrically or autogenously, though electrical welding is preferred.
- Autogenous welding risks manganese and carbon burn-off.
Recommended Materials
- Shielded electrodes with 0.8%-1.0% carbonio e 15%-18% manganese are used for electric welding.
- Weld seams exhibit slightly lower wear resistance compared to the base material.

Riepilogo

X120MN12 manganese steel excels in applications requiring high wear resistance and impact durability. Its ability to strengthen through cold working and compatibility with various fabrication processes make it a reliable choice in heavy-duty industries.
