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.CARBOLOY Grade 370 is a tough, wear-resistant grade of cemented carbide for heavy-duty roughing cuts. It successfully withstands the high temperatures encountered in heavy-duty machining of steels, ferrous casting, stainless steels and some high-temperature alloys.
