Description

Stainless steel for the injection moulding of corrosive plastics. This is the most advanced steel for overcoming the most demanding applications. The exceptional corrosion resistance in combination with a hardness of approximately 50 HRC makes it an ideal choice for injection moulding of reinforced plastics, medical parts, PVC and rubber. Due to its extraordinary resistance to corrosion, it allows a drastic reduction of maintenance costs and an increase of the series. Being a precipitation hardening steel, it is extremely simple to obtain hardness within the range of 32 to 50 HRC.

Main applications

  • Plastic injection moulds with high corrosion resistance in which very low deformation is desired during the heat treatment
