Abstract
Medium manganese steel was produced by reducing carbon and manganese content of the high -manganese steel. Research results show that the matrix after water quench at the temperatures of 1050~1070 ℃ is austenite carbide (+0 ~W2 class). The medium manganese steel, whose wear resistance is better than that of the high manganese steel, can meet the requirements of strength and toughness in the non -working strong -impact conditions. The casting cost for medium manganese steel is 420 CNY lower than that of the high manganese steel. The service life of the former is 16 % longer that of the latter.
