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.AISI 1117 is a resulfurized carbon steel for use where a free-machining carburizing steel is required. Its manganese content (nominally 1.15%) provides some increase in hardenability in all applications and increased hardness and strength in uncarburized uses and in the core of carburized parts. Its applications include a wide range of components of components and parts for machinery and structures.
