Following the tests reported previously, the abrasion tests on high manganese steels of various components were conducted by means of a tube-mill type abrasion tester. The results are summarized as follows : (1) As to the effect of heat treatment on the wear resisting property of the ordinary high manganese steel, a good result is obtained in the case of 250℃ tempering after quenched into water (even though is not so much difference as compared with quenched ones), and the characteristics become worse when the tempering temperature rises to 650℃. (2) The wear resisting property is adversely affected by adding the silicon content in the ordinary high manganese steel. (3) And also adding of chromium content is no good for the wear resisting property. (4) The special manufactured high manganese steel shows excellent wear resistance notwithstanding its chemical composition which is not so different from that of ordinary high manganese steel. (5) The result reported in the previous report, that the steel of large grain size is inferior to the steel of small grain size in the wear resisting property, is applied in this case. (6) The relation between the wearing time and the amount of wear may be formularized experimentally as the formula (1), and in this case the constants in the formula show nearly constant values regardless of the quality of each material. (7) The relation between the wearing time and the hardness is closely connected. The formula (2), and the constants in the formula are nearly equal in each material, and agree with the previous result that the increase of hardness with wearing time is very remarkable as compared with the carbon steel.
