Plastic mould steels - Hardenable, corrosion-resistant steels

The processing of fibre-reinforced plastics requires hardenable, corrosion-resistant tool steels with a high carbide content, approx. 13 to 20 % Chromium, additions of Molybdenum, Tungsten and Vanadium and a hardness of 50 to over 60 HRC. In High-Nitrogen Steels, Carbon is partially replaced by Nitrogen to achieve a hardness of approx. 58 HRC with the best corrosion resistance.
