X120MN12グレードのマンガンプレートとシート

X120MN12マンガン鋼, ハードマンガンスチールとも呼ばれます, 独自のプロパティで有名です. It becomes significantly harder and more wear-resistant through intense cold working while maintaining high durability.

主な特長

• 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.
• Versatility
  • 素材は曲げることができます, フランジ付き, and pierced due to its excellent flexibility.
  • Chipping at room temperature is possible but limited, requiring hard metal tools.

代表的な用途

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

• Hangers in blasting machines
• Crusher jaws and inserts
• Power shovel bolts and connectors
• Gripping teeth
• Impact and centrifugal mills
• Protective grills, 被覆材, 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% carbon and 15%-18% manganese are used for electric welding.
  • Weld seams exhibit slightly lower wear resistance compared to the base material.

まとめ

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.
