In order to find out the defacement prevention effect of the material when it is used for points of the railway, the author conducted a test, using an Amsler-type abrasion testing machine, at slip velocities of or 15cm/sec, and under contact pressures of 50∼90kg/mm2.
The test piece of type is about 0.7%C standard structure steel, and the other materials of deposited weld metals are austenitic high manganese steel, high Mn-Cr steel, high Mn-Ni steel, and high Mn-Mo steel etc.
The result of this test shows, in case of austenitic structure of deposited weld high manganese metal, the same tendency of wear as high manganese steel.
