The high manganese steel containing 0.8〜1.2%C and 10〜14% Mn is generally used for the wear resisting steel which is very tough if it is treated by the so-called water-toughening. To find out prevention method of defacement i case of being used for points of the railway, I make an experiment, using Amsler-type abrasion testing machine, and at slip velocities of 0〜15 cm/sec and contact pressures of 60〜110 kg/mm^2. The test piece of tyre in my test is about 0.7%C standard structure steel and the other material of high manganese steel is from 1050℃ water-toughening. The following are the findings resulted from the present test : 1) No satisfactory effect could be obtained owing to adhereing phenomenon between carbon-steel and high manganese steel. 2) High manganese steels which is low in surface hardness (H_3<60) is not so effective to reduce wearing as we expect. 3) From these facts, high manganese steel seems to be superior for its anti-shock toughness than its preventive effect for wearing.
