Hadfield austenitic manganese steels exhibits high toughness, high ductility, high work hardening ability and excellent wear resistance. Because of the excellent combination of these properties this steel has been accepted as a very useful engineering material. It is broadly used in the fields of earthmoving, mining, quarrying, oil well drilling, steelmaking, railroading, dredging, naval, lumbering excavators, and mineral crushing equipment. In this study the influence of various contact molybdenum on the microstructure and mechanical behavior of this alloy was investigated. The results are described and discussed using micro-hardness measurements, impact test, optical and scanning electronic microscopy and EDS analyses.
