Cutting Tool Applications, Chapter 1: Cutting Tool ...

The alloying elements in HSS - principally cobalt, chromium, and tungsten - improve the cutting properties sufficiently, that metallurgical researchers developed the cast alloys, a family of materials without iron. A typical composition for this class was 45% cobalt, 32% chromium, 21% tungsten, and 2% carbon. The purpose was to obtain a cutting tool with hot hardness superior to HSS. When ...
