锰含量为13%、碳含量为1%的哈德菲尔德(Hadfield)高锰钢,由于其耐磨性好,早就深为人们所重视。但是,这种钢材磁稳定性差,热膨胀系数大,热加工性和被切削性均比18—8不锈钢差得多。最近研制出一种无磁性高锰钢,不仅价格低廉,而且即使在加工和热处理时,也可保持非磁性状态,在低温条件下,也具有优良的机械性能。这种钢的成分配方主要是以提高抗 Hadfield high manganese steel with a manganese content of 13% and a carbon content of 1% has long been highly regarded due to its good wear resistance. However, this steel has poor magnetic stability, a large coefficient of thermal expansion, poor hot workability and machinability compared with 18-8 stainless steel. Recently developed a non-magnetic high manganese steel, not only cheap, and even in the processing and heat treatment can also maintain a non-magnetic state, at low temperatures, but also has excellent mechanical properties. The composition of this steel recipe is mainly to improve resistance
