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 Type T4 is made by adding 5% cobalt to the conventional 18% tungsten-4% chromium-1% vanadium (AISI Type T1) tool steel. The cobalt dissolves in the ferrite and strengthens the matrix of the steel whereas the other alloying elements form carbides. Thus the cobalt increases the hot or red hardness, thereby enabling the tool to maintain a higher hardness at elevated temperatures. Type T4 is recommended for hogging cuts with heavy-duty lathe, planer and boring tools, or where the temperature of the cutting point of the tool is increased greatly. It is well adapted for cutting hard, gritty materials such as cast iron or other abrasive materials and for cutting nonferrous alloys at high speeds.
