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.JESSOP CNSI is a high-carbon, high-chromium tool steel possessing outstanding resistance to wear. It air hardens with a minimum amount of distortion; it also may be oil hardened. Its analysis is balanced to give maximum hardness and toughness. It is recommended for general-purpose work where high wear resistance combined with shock resistance is needed. Its many applications include dies of many types, cutters, punches, brick molds, rolls, taps, knurls, forming tools and reamers.
