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.CANNON-MUSKEGON A-2 is a high-carbon air-hardening cast tool steel with excellent non-deforming properties and abrasion resistance in the quenched and tempered condition. It has good machinability in the annealed condition. A higher silicon content is permissible in this cast steel than in AISI A2 (wrought) tool steel.
