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.UHB STAVAX ESR is a high-chromium (13.6%) martensitic stainless plastic-mold steel. It is Electro-Slag Refined (ESR) to provide the best polishability. It is characterized by good hardenability, high hardness, excellent polishability and fair resistance to corrosion. It is used for both injection and compression plastic molds.
