View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.CORRAX is a precipitation-hardening (PH) stainless mold steel that may be used for many demanding applications. Its superior resistance to corrosion, combined with a hardness of up to 50 HRC, makes it well suited for molds making medical parts, all molds running in a clean-room environment, parts made of corrosive plastics (such as polyvinyl chloride, PVC), and molds for parts made of rubber.
