Shanghai Metal Corporation supply a wide range of quality tool steel,
such as H3, H13, H11, H21 etc, which are highly acclaimed by our international customers
due to its durability and similar other attributes
Manufacturing of Tool Steel Bar:
- Cold rolling, slitting and edge processing
- Heat treatment: annealing, tempering, hardening
- Cold finishing and polishing
Normalizing temperature: 860-900oC.
Heat to 760-800oC, cool slowly in furnace.
This will produce a maximum Brinell hardness of 217.
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.
Harden from a temperature of 830-890oC followed by oil quenching.
Hardness after quenching is approx. 64 HRC.
Tempering temperature: 150-180oC.
