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.CARPENTER U.D.R. is a low-chromium (nominally 0.50%) alloy steel made to the quality standards of tool steels. It was developed to meet the exacting standards of bearing manufacturers for a clean steel of uniform microstructure.
