To find out the prevention of defacement in case of being used for the point or railway, I carried out an experiment under the following conditions, using an Amsler-type abrasion testing machine, at various slip speed of 0〜15 cm/sec, and contact pressures of 50〜90 kg/mm^2. The test tiece of tyre is about 0.7%C steel of standard structure, and the other material of High manganese steel and Chrome-mangan steel is from 1050℃ water-hardning. The following are the findings result from the present test : 1. Hardness of High mangabese steel goes up to a certain extent at the beginning of the test. However, anti-wearing character can not be expected to increase owing to the growing of its hardness. 2. Satisfactory effect of wear resistivity can not be expected much in the sliding motion between C-steel and High manganese steel due to sliding friction. 3. From these facts, High manganese steel seems to be superior in anti-shock toughness than in wear resistivity. 4. Chrome-mangan, which somewhat covers for the effects of High manganese steel, in somecase must be used carefully within the limit of its application. 5. In this case, the actual amount of the wear can be estimated by this tests.
