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 1526 is a carbon steel containing relatively high manganese (1.10 to 1.40%) and low-to-medium carbon. It combines good machinability, good workability and good weldability. It may be used in hot-rolled, annealed, normalized or liquid quenched-and-tempered condition for a wide range of applications. Also, it may be case hardened by carburizing. Its high manganese content provides increased hardenability which is reflected in all uses and gives increased strength in the core of carburized parts and in uncarburized applications.
