HSS T4 bars W18Co5 steel 1.3255 steel bar

 

Steel 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 600-650oC, 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 600-650oC, 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 560-580oC. Hardness after tempering is 64-65 HRC.
