• Steam oxide treated to reduce wear and chip welding in harder ferrous materials
• Steam tempering gives a strongly adhering blue oxide surface that acts to retain cutting fluid and prevent chip to tool welding, thereby counteracting the formation of a built-up edge
• Steam tempering can be applied to any bright tool but is most effective on drills and taps
• A medium alloyed high speed steel that has good machinability and good performance
• HSS exhibits hardness, toughness and wear resistance characteristics that make it attractive in a wide range of applications
