T1 High Speed Steel
T1 steel is a typical Tungsten-type high speed tool steel according to ASTM standard.It has good comprehensive performance. T1 hss steel has a high hardness (HRC62~66), strength, toughness and heat resistance.The red hardness of T1 tool steel can reach 620°C.It’s cutting edge can be more sharp. AISI T1 high-speed steel has strong commonality. However its strength with cross section dimension decreases a lot.
Carbon: 0.65/0.80; Chromium: 3.75/4.50;
Vanadium: 0.90/1.30; Tungsten: 17.25/18.75;

5.AISI T1 HSS Steel Applications
T1 high speed steel is widely used in drill bits, milling cutter, broach, gear cutting tools, such as tap complex cutting tool manufacturing.
1)Preheat T1 high speed steel uniformly and slowly to 850-880°C.
2) Increase the forging temperature until 1050-1130°C.
3)T1 tool steel should be cooled very slowly after forging.
T1 steel should be annealed after hot working. Increase the temperature of T1 high speed steel to 850°C at a rate of Max220°C per hour. Hold at the temperature and then cool slowly in the furnace. The annealed hardness achieved will be below 255 HB.
1)Preheat T1 hss steel to 480-500°C ;
2)Increase the temperature up to 860-900°C;
3)Heating the hardening temperature to 1200°C;
4)T1 high speed steel must be heated through;
5)Quench in the warm oil or brine,and then complete the quench;
6) T1 tool steel is suitable for vacuum hardening.
1)Temper T1 high-speed steel 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 T1 tool steel.
