Specifications of Tool Steel Bar:

Heat Treatment:

Normalizing:

Normalizing temperature: 860-900oC.

Soft Annealing:

Heat to 760-800oC, cool slowly in furnace

This will produce a maximum Brinell hardness of 217

Stress Relieving:

Stress relieving to remove machining stresses should be carried out

by heating to approx. 650oC, holding for 1-2 hours at heat, followed by

air cooling. This operation is performed to reduce distortion during heat treatment.

Hardening:

Harden from a temperature of 830-890oC followed by oil quenching

Hardness after quenching is approx. 64 HRC

Tempering:

Tempering temperature: 150-180oC

 

Manufacturing of Tool Steel Bar

a) Cold rolling, slitting and edge processing

b) Heat treatment: annealing, tempering, hardening

c) Cold finishing and polishing
