Annealing:Annealing temperature: 710 ~ 740 °C, holding time is decided by the thickness of the DIN 1.2738 die steel, one hour per 25mm. Colding in furnace after thermal insulation.
Destressing: Heating temperature: 600 °C (annealed condition), 550 °C (quenching and tempering state), holding time is decided by the thickness of the 1.2738 steel, one hour per 50mm. Colding in furnace after thermal insulation.
Quenching and tempering:
Preheating temperature 500 ~ 600 °C, quenching temperature 840 ~ 880 °C, holding 30min (the mold have to quenching in the protective gas to prevent oxidation and decarbonization). Oil cooling, cooling to 50 ~ 70 °C,immediately tempered. Tempering holding time is decided by the thickness of the 1.2738 steel mould, one hour per 25mm, at least 2h. Tempering temperature: 180 °C / 200 °C / 300 °C / 400 °C / 500 °C / 600 °C, the hardness: 52HRC / 51HRC / 48 HRC / 46HRC / 42HRC / 34HRC.
Large plastic moulds with deep engravings and intensive impacts on the core. 1.2738 Pre
hardened Plastic Mold Steel is the logical development of 1.2311, a pre-hardened plastic mould steel for use in large moulds, which also have to display high core strength. The additional nickel content of 1 % increases through hardening. 1.2738 is a micro-alloyed, vacuum-degassed steel with the following excellent features: good machinability, outstanding polishability, good texturing properties.
1.2738 Pre-hardened Plastic Mould Steel, hardness in as-delivered condition 280 to 325 HB. Good machinability, suitable for texturing, improved through hardening in comparison to 1.2311, good polishability.
