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.GUTERL T-1 is a general-purpose high-speed steel that is suitable for practically all high-speed applications. It is relatively easy to fabricate. This steel has been the standard of the industry for many years because of its excellent combination of cutting ability and toughness, ease of heat treatment and minimum tendency to decarburize. Its many uses include drills, taps, broaches, hobs, lathe and planer tools, milling cutters and wood-working tools.
