Influence of Carbides and Strain-induced Martensite on Wear Resistance of Austenitic Medium Manganese Steels

The abrasive wear behaviour of austenitic medium manganese steels was studied under weak corrosion-abrasive wear simulating the liner plate in wet metallic ore bail mill under non-severe impact-loading working condition. Results show that the work-hardening mechanism and the wear resistance of high carbon austenitic medium manganese steels differ from those of medium carbon austenitic medium manganese steel. Under non-severe impact and weak corrosion-abrasive wear,the wear resistances of high carbon and medium carbon austenitic medium manganese steels are 50-90% and 20-40% higher than that of Hadfield steel respectively.
