Mild steel (carbon content 0.2% and 0.4%) was scratched with the tungsten carbide triangular and quadrangular pyramid chisel at the rate of 130-185m/min by means of the pendulum type scratch test machine at room temperature, 150℃, 300℃, 500℃ and 650℃. Results of the tests are as follows : 1. The smaller the depth of scratch is, the larger becomes the specific scratch resistance. 2. The specific scratch resistance is 4.5-2×10^3kg/mm^2 at room temperature, when mean depth of scratch is 2-6.5μ. 3. Compared with the specific scratch resistance at room temperature, it becomes a little larger at 150℃, considerably larger at 300℃, a little smaller at 500℃, and considerably smaller at 650℃.
