1.3343 high speed steel

1.3343 high speed steel is the most commonly used, conventionally manufactured, medium-alloy high-speed steel and is universally applicable for tools of all kinds.

Otherwise known as M2 steel, it can be characterised by a ≤260HB delivery condition hardness and an achievable hardness after treatment of ≤65Hrc. It is one of the most popular tungsten-molybdenum tool steels The HSS chemical composition gives a good combination of well-balanced toughness, wear resistance and red hardness properties. Widely used for cutting tools such as twist drills, taps, milling cutters, saws, knives etc. Also commonly used in cold work punches and dies and cutting applications involving high speed and light cuts.
