||DuraTech T15 powder metallurgy high speed steel is cobalt-bearing super high speed steel which can be heat treated to a hardness as high as 67 Rockwell C. A high volume of hard vanadium carbides provides very high wear resistance. The cobalt content provides excellent resistance to softening at high service temperatures (red or hot hardness). These properties translate into extended retention of hard, sharp cutting edges on tools produced from DuraTech T15. Because of the powder metal (PM) manufacturing, DuraTech T15 is far easier to grind and exhibits impact toughness that is more than double that of traditional, ingot-cast T15 high speed steel. Typical tooling applications in which DuraTech T15 excels include high-performance
broaches, form tools, milling cutters, end mills, taps, and reamers. DuraTech T15 is the high speed steel of choice for any cutting application on strong or abrasive materials that generate high cutting tool temperatures.
