Hardenable corrosion resistant steels

The processing of plastics which contain chemically aggressive or abrasive fi llers demands hardenable, corrosion-resistant steels. This reduces the mould maintenance necessary in comparison to steels which are less corrosion resistant.
Hardenable steels: Steels which are delivered in the soft annealed condition and usually hardened to over 50 HRc after machining.
