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.Dual-phase (DP) steels are one of the important new advanced high-strength steel (AHSS) products developed for the automotive industry. Their microstructure typically consists of a soft ferrite phase with dispersed islands of a hard martensite phase. The martensite phase is substantially stronger than the ferrite phase. The dual-phase grades, including those with high tensile strengths of 965 MPa (140 ksi), that are designed for forming (DI-FORM), also have low yield-strength-to-tensile-strength ratios to improve formability.
