M2 High Speed Steel
As a general purpose high speed tool steel,it is commonly used in tool bits,cutting tools, power-saw blades,drill bits and cold forming tools.HSS can withstand higher temperatures without losing its temper.This property allows HSS to cut faster than other tool steels.HSS grades generally display high hardness,toughness and abrasion resistance.
Carbon: 0.78/0.88; Chromium: 3.75/4.50; Molybdenum: 4.50/5.50;

5.M2 HSS Applications
M2 high speed steel is widely used in broaches, milling tools, metal saws, twist drills, reamers.M2 hss is fit for cold forming tools such as plastic moulds,screw dies,Slotting tools and cold extrusion punches and cold work dies.
1)Preheat M2 high speed tool steel uniformly and slowly to 850-900°C.
2) Increase the forging temperature more quickly to 1050-1150°C.
3)M2 tool steel should be cooled very slowly after forging.
M2 is annealed after hot working. Increase the temperature of M2 high speed steel to 850°C at a rate of Max220°C per hour. Hold at the temperature and then furnace cool slowly. The annealed hardness achieved should be Max255 Brinell.
1)Preheat M2 hss too steel to 450-500°C ;
2) Increase the temperature to 850-900°C;
3)Heating the hardening temperature to 1200-1250°C;
4)The M2 high speed steel component must be heated through;
5)Quench in the warm oil or brine,and then complete the quench in air;
6) M2 high speed steel is suitable for vacuum hardening,too.
1)Temper M2 hss immediately after quenching;
2)Heat thoroughly and uniformly to the tempering temperature;
3)Hold for at least two hours (one hour per 25mm);
4)Triple tempering is strongly recommended for M2 high speed steel.
