The high manganese steel containing 0・8-1・2 C and 10〜14% Mn is generally used as the wear resisting steel which is very though when melt-up on the mild-steel by hard-faceing method. To find out the prevention method of defacement in case of being used for points of the railway, I examined the following condition, using Amsler-type abrasion testing machine, at slip velocities of 0〜15cm/sec and contact pressures of 40〜90 kg/mm^2. The test piece of tyre in my test is of 0・69%C standard structure steel and the other rail of 0・53% 0・71%C steel and high manganese steel, and rail specimen are of the next four cases. i. e. Case-1 0・53%C standard structure steel Case-2 0・71%C standard structure steel Case-3 0・71%C Steel Oil-heat-treated in 800℃ and 400℃ temper Case-4 0・82%C, 13・35%Mn chamical component steel as melt-up. As a result, I am convinced that for the prevention of defacement case-4 is most effective, and the result of this case accords precisely with the deta on the actual condition of defacement.
