5. 1.3343 HSS Applications
1.3343 high speed steel is usually used in drill bits,broaches, milling tools, reamers. 1.3343 hss is also fit for cold forming tools such as plastic moulds,screw dies,Slotting tools and cold extrusion punches and cold work dies.
1)Preheat 1.3343 high speed steel slowly to 850-900°C.
2) Increase the forging temperature to 1050-1150°C.
3)During the forging,if the temperature of the material drops below 900°C, re heating it.
4)1.3343 tool steel should be cooled slowly after forging.
1.3343 should be annealed after hot working. Increase the temperature to 850°C at a rate of Max220°C per hour. Keep at this temperature and then furnace cool uniformly.The annealed hardness achieved should be Max255 HB.
1)Preheat 1.3343 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 1.3343 high speed steel should be heated through;
5)Quench in the brine,then complete the quench in the air;
6)1.3343 high speed steel is suitable for vacuum hardening.
1)Temper 1.3343 hss immediately after quenching;
2)Heat thoroughly and uniformly to the tempering temperature;
3)Hold for at least two hours;
4)Triple tempering is recommended for 1.3343 high speed tool steel.
