ASTM T5 high speed tool steel is one of special steel. It belongs to ASTM A600, together with T1, T2, T4 Tool Steel etc. They also in T group in ASTM A600 standard. AISI T5 high speed steel contains Cobalt with range 7.0~9.5%.
IBC Metal Group, AISI T5 high speed tool steel manufacturers and suppliers, supplied in round bar, square bar, flat bar, plate, sheet and wire. AISI T5 steel has better high temperature performance, toughness and better cutting performance than ASTM T4 steel. Similar to T4 steel materials, T5 tool steels are also used for cutting tool, turning tool etc. Compared with AISI T4, it has higher cobalt with 8%, which makes higher temperature performance and better toughness. It also has high abrasion resistance and good cutting performance. The surface hardness can reach 68-70HRC after quenched.

Forging of ASTM T5 Tool Steel Materials
Hot forming temperature: 1150-900℃.
ASTM T5 Tool Steel Heat Treatment
- Annealing of T-5 Steel —— Annealing is recommended after hot working and before re hardening
- Heat the temperature to 850°C at a rate of no more than 220°C per hour. Hold at the temperature for one hour per inch of thickness (at least two hours). Cool slowly in the furnace or in air to ambient temperature. The resultant hardness achieved should be Max 255HB or lower.
- Stress Relieving —— Stress relieving to remove machining stresses should be carried out by heating to 600-650℃, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
- Hardening of Steel T5 —— Preheat T5 tool steel slowly to the temperature of 820-870°C.
- Heat to the final hardening temperature of 1250°C and make sure the material must be heated through.
- Quench in the warm oil, and then complete the quench in air. (care must be taken at this step)
- Tempering of T-5 Steel —— Tempering temperature: 550-590℃.

Applications of ASTM/AISI T5 Tool Steel
Typical applications are: Drills; Milling Cutters; Thread Cutting Tools; Knurling Tools; Cold extrusion punches and Broaches etc. ASTM T5 high speed steels is good for machining high strength steel, high temperature alloy, titanium alloys, casting alloy materials and other difficult-to-machine materials. And also widely used in cutting tools, broaches, extrusion punches, punchers, turning blades, metal working blades, milling cutter, drill,and etc.
