T1 High Speed Steel
T1 high speed tool steel manufacturers and suppliers, supplied in round rods,flat/square bars,plates,sheets,wire and blocks.
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.

| Annealing 1.Annealing is recommended after hot working and before re hardening 2.Heat the temperature to 850°C at a rate of no more than 220°C per hour. 3.Hold at the temperature for one hour per inch of thickness(at least two hours). 4.Cool slowly in the furnace or in air to ambient temperature. 5.The resultant hardness achieved should be Max 255HB or lower. Hardening 1.Preheat T1 to 480-500°C ,then up to 880-900°C. 2.Heat to the final hardening temperature of 1200°C and make sure the material must be heated through. 3.Quench in the warm oil,and then complete the quench in air.(care must be taken at this step) 4.T1tool steel is suitable for vacuum hardening. Tempering 1.Tempering must be done immediately after quenching. 2.Heat thoroughly and uniformly to the tempering temperature 3.Hold at the temperature for at least two hours (one hour per inch of the total thickness). 4.Triple tempering is strongly recommended for T1 tool steel. | |||||||
