Mixtures of stainless steel powders and non-metal additives were sintered and those materials were cut, then, the progress of tool wear in cutting were examined. The most effective additives to prolong tool life were found. The conclusions obtained in the experiment are as follows. (1) The most effective additive was boron nitride. (2) The addition of a few volume percent of boron nitride to stainless steel made the tool life a hundred times longer than in stainless steel without additives. (3) By addition of a boron nitride and glass mixture to stainless steel, tool life was prolonged still more.
