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.Finkl ShelleX is a high-quality steel alloy melted, vacuum arc degassed, and forged. The alloy is similar to Shelldie (see Alloy Digest SA-36) but has nearly twice the molybdenum content for excellent wear resistance under conditions of high die operating temperatures. The alloy is suitable for hydraulic and mechanical presses. Die preheating is mandatory. The alloy is used for die inserts or other applications where higher wear and tempering resistance that H11 or H13 die steels have is important.
