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 its durability and similar 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 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
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 Bar
Shanghai Metal Products are packed and labeled according to the regulations and customer's 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 the product I. D. and quality information.
