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.PRESTO is a high-carbon tool steel containing 1.40% chromium and is moderately deep hardening. It is made to tool-steel-quality standards and was developed to meet the exacting demands of bearing manufacturers for a clean steel of uniform microstructure. It is used in a wide range of bearing applications including high-performance aircraft bearings and other high-load applications where high-quality steel is required.
