7Mn15Cr2Al3V2WMo钢板#无磁性钢板
7 mn15cr2al3v2wmo high manganese steel is a kind of Mo - V without magnetic steel. The steel under various condition can keep stable austenite and very low permeability, high hardness, strength, good abrasion resistance. Due to the cold work hardening of high manganese steel, cutting processing more difficult. High temperature annealing process is proposed, which can change the particle size, shape and distribution of the carbide state, which significantly improve the cutting performance of steel. Using gas soft oxidation process, and further improve the surface hardness of steel, increasing wear resistance, improve the service life of parts. The steel is suitable for manufacturing magnetic mold, magnetic bearing and she requires in strong magnetic field does not produce magnetic structure parts. In addition because the steel with high strength and hardness at high temperatures, can also be used to manufacture under 700 ℃ ~ 800 ℃ using hot-work mold.
7Mn15Cr2Al3V2WMo锰钢是一种高Mo-V系无磁钢。该钢在各种状态下都能保持稳定的奥氏体，具有非常低的磁导系数，高的硬度、强度，较好的耐磨性。由于高锰钢的冷作硬化现象，切削加工比较困难。采用高温退火工艺，可以改变碳化物的颗粒尺寸、形状与分布状态，从而明显地改善钢的切削性能。采用气体软氧化工艺，进一步提高钢的表面硬度，增加耐磨性，显著提高零件的使用寿命。该钢适于制造无磁模具、无磁轴承及其她要求在强磁场中不产生磁感应的结构零件。此外由于此钢还具有高的高温强度和硬度，也可以用来制造在700℃～800℃以下使用的热作模具。
