718 P20+Ni 1.2738 Pre-hardened Plastic Mold Steel Block

Introduction

1.2738 Pre-hardened Plastic Mold 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.

Applications

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. Formadur 2738 ia a micro-alloyed, vacuum-degassed steel with the following excellent features: good machinability, outstanding polishability, good texturing properties.
