Tool Steel

We are offering m2 high speed steel as a tungsten molybdenum, general purpose high speed steel, it is widely used in the production of machine tool bits, cold forming tools and cutting tools. And m2 high speed steel offers high toughness combined with good cutting powers and will withstand increases in temperature without losing its temper. M2 high speed steel also is classified as a "medium" machinability tool steel in the annealed condition. It may be shaped by grinding but is relatively poor in regard to capability of being ground.
Features
1 . Fushun special steel is suppliers of m2 high speed steel in round bar, sheet and plate which can be bandsaw cut to your specific requirements.
2 . M2 high speed steel is a higher carbon version of the m1 tool steel (molybdenum high speed tool steel).
3 . M2 high speed steel alloy has somewhat better wear resistance than m1.

applications
typical applications for m2 high speed steel are twist drills, reamers, broaching tools, taps, milling tools, metal saws. M2 high speed steel is suitable for cold forming tools such as extrusion rams and dies, also cutting tools, plastic moulds with elevated wear resistance and screws .
Heat treatment
preheat at 1450 f before heating for hardening. Then heat rapidly from 1450 f to 2200 f and hold for 3 to 5 minutes followed by quenching in oil, air or salt bath.
