AISI T4 steel DIN 1.3255 bars W18Cr4VCo5 steel china price per ton

a.Description:

This alloy is a High Speed, tungsten type tool steel. It is a deep hardening alloy capable of Rockwell C 64 hardness.

Applications:
Generally used as cutting tools, broaches and cold extrusion punches, turning and milling cutters for roughing work. 

Soft Annealing:

Heat to 820-850°C, cool slowly in furnace to 550°C then air. This will produce the maximum Brinell Hardness of 265.

Stress:

Stress relieving to remove machining stresses should be carried out by heating to 600-650^oC, holding for one hour at heat, followed by aircooling. This operation is performed to reduce distortion during heat treatment.

Hardening:

Stress relieving to remove machining stresses should be carried out by heating to 600-650^oC, holding for one hour at heat, followed by aircooling. This operation should be performed to reduce distortion during heat treatment.

Tempering:

Tempering temperature: 2 x 560-580^oC. Hardness after tempering is 64-65 HRC.
