(HSS) High Speed Steel material composite is W6Mo5Cr4V2, consisting of Tungsten, Vanadium, Molybdenum, Chromium, Sulfur, Phosphorus, Manganese, Silicon & Carbon. These HSS tools have a very high resistance to wear & softening at high temperatures whilst maintaining a good toughness on the cutting edge, that's very crucial in a good quality turning tool as it keeps its edge sharper than normal carbon steel by a ratio of ten to one.
