MN13 고-망간 내건 저항성 강철: 특징 및 처리 안내서
개요
Mn13 is a high-manganese steel known for exceptional wear resistance, 충격 및 고압 응용 프로그램에 이상적입니다. 두 가지 주요 특성은 다음과 같습니다.:
- 더 큰 충격으로 내마모성 향상.
- 표면이 마모됨에 따라 지속적으로 경화층이 형성됨.
고크롬 주철과 달리, 슬라이딩 마모에만 저항하는, Mn13 steel is also highly effective against impact and high-stress wear. It offers easy machinability, 절단을 포함하여, 용접, and bending. By using Mn13, costs for equipment wear and maintenance can be significantly reduced.
주요 장점
- 절단
- 플라즈마 절단: 플라즈마 절단, especially underwater, is recommended for Mn13. Underwater plasma cutting heats the steel plate to thousands of degrees, melting the surface quickly and preventing oxidation with water cooling. This results in a smooth, flat surface without heat-affected zones. Air plasma cutting is also an option.
- 불꽃 절단: Traditional flame cutting can be used with a cutting trolley. Select the appropriate nozzle size and adjust the gas-to-oxygen ratio (a neutral flame works best). Complete all adjustments before starting to prevent cross-section gaps.
- 용접
Mn13 steel plates can be welded using manual arc welding. Prepare by cleaning the weld area to remove rust and oil. Use a small-diameter electrode (3–3.5mm), small current, and high voltage for multi-layer, fast welding. For DC welding, connect the electrode to the positive pole. Hammer each weld layer to improve crack resistance, and cool with water if needed.
Mn13 steel’s wear resistance, combined with easy machinability, makes it an excellent choice for extending the life and efficiency of equipment components.
