Shanghai Metal Corporation supplies a wide range of quality tool steel
such as H3, H13, H11, H21, etc. which are highly acclaimed by our
international customers due to their durability and various other attributes.
Specifications of Tool Steel Bar:
Normalizing temperature: 860-900oC.
Heat to 760-800oC, cool slowly in furnace
This will produce a maximum Brinell hardness of 217
Stress relieving should be carried out in order to remove machining
stresses by heating to approx. 650oC, holding for 1-2 hours at heat,
and allowing 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: 150-180o C
Manufacturing of Tool Steel Bar
a) Cold rolling, slitting, and edge processing
b) Heat treatment: annealing, tempering, hardening
c) Cold finishing and polishing
Packaging of Tool Steel Bars:
Shanghai Metal Products are packed and labeled according to regulations and customer requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of product and quality information.
