The high manganese steel containing 0・8 to l・3% and 10 to 14% Mn is generally used for the wear resisting steel which is very tough if it is treated by the so-called water toughening. Devising a tube-mill type abrasion tester we performed abrasion tests on high manganese steels of various components, and an outline of the results is given in this paper. As we know that the initial grain size of the austenite has a greater effect on the wear resisting property of the material than other chemical components such as Mn, C and etc. and that the steel of large grain size is inferior to the steel of small grain size in the near resisting property, we shonld pay strict attention to the factors controlling the grain size in manufacturing steel. When the size of the grain is nearly equal, steel contaming about 12% Mn is in general most resistive against wear in the experimental scope.
