Dry and wet wear test of high chromium cast irons and high speed steel type alloys containing high carbon was carried out by using the pot mill type wear testing apparatus. Specimens were cast into sand mould, machined and heat treated. A specimen and forty three ceramic balls in a pot were rotated at the speed of 1.67 rev. per sec. for 3.6×10^2ks in dry wear test. In wet wear test, a specimen, 43 ceramic balls and sea water in a pot were done in same rotating condition as that of dry wear condition. Weight loss of specimens was measured and evaluated as wear loss. In dry wear condition, wear loss of high speed steel type alloys containing high carbon was smaller than that of high chromium cast irons. Wear loss of high speed steel type alloys with high carbon was larger than that of high chromium cast iron in wet wear condition. It was because high chromium cast iron had more excellent corrosion resistance than that of high speed steel type alloys containing high carbon. Wet wear was accelerated by corrosion of specimens. Static toughness (K_Q) obtained by bending test was in the range from 22 to 37MPa √<m> and it decreased with an increase in amount of crystallized carbides.
