Material Notes:
High chromium-vanadium-molybdenum alloyed steelA through-hardening corrosion resistant mold steel made by powder metallurgy processing techniques. The high wear resistance makes ELMAX® suitable for long production runs; e.g. electronic parts.ELMAX® is characterized by: High wear resistance High compressive strength Corrosion resistant Very good dimensional stabilityApplications: New types of engineering plastics, with high filler contents, place greater demands on the tooling material, in terms of wear resistance and corrosion resistance. Uddeholm Elmax has been specially developed for high-tech applications. These include products within the electronic industry such as connectors, plugs, switches, resistors, integrated circuits, etc. Uddeholm Elmax can also be used in the food processing industry and for industrial and custom knives, where a combination of corrosion resistance and wear resistance is required
