PLASTIC MOULDING STEEL
PLASTIC MOULDING STEEL
DIN 1.2311
Steel properties : pre – hardened plastic mould steel, hardness in as delivered condition 280 to 325 HB, good machinability, suitable for texturing, better
polishability.
Applications: plastic moulds, mould frames for plastic mould and pressure
casting moulds and recipient sleeves.

DIN 1.2738
Steel properties : pre – hardened plastic mould steel with 1% Nickle condition 280 to 325 HB, good machinability, suitable for texturing, good polishability also available with hardness of 360 – 400HB
Applications: Large plastic moulds with deep engravings and intensive impacts on the core. 1.2738 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 to 1 % increase through hardening. 1.2738 is a micro –alloyed, vaccum – degassed steel with the following excellent features : good machinability, outstanding polishability, good texturing properties.
