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.AL TECH HURON is a cold-work tool steel developed for applications requiring high resistance to wear or to abrasion and for resistance to heavy pressure rather than to sudden shock. Because of these qualities and its good nondeforming properties, it is unsurpassed (for an oil-hardening tool steel) for die work on long production runs. It has superior depth of hardening. Its many applications include cold trimmer dies, lamination dies, plug gages, slitting cutters and blanking, stamping and cold-forming dies and punches for long runs.
