Product Description
SKH4 BT5 1.3265 T5 High Speed Steel Round Bar
1: AISI T5 Steel Introduction
AISI T5 tool steel is one of tungsten type high speed tool steel, which belongs to ASTM A600specification, the standard for high speed tool steel materials. T4 tool steel is similar to T1 Tool Steel materials, but with 4.25~5.75% cobalt added to increase heat resistance. The red hardness of T4 steel and the high temperature hardness is a little higher than T1 tool steel. AISI T4 tool steel is a deep hardening alloy capable of Rockwell C 64 hardness.

8: AISI T5 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 600-650oC, 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: 550-590oC.
