MITTAL DI-FORM T780, T980: Dual-Phase Steel

MITTAL DI-FORM T780 and T980 alloys are low-carbon steels with a manganese and silicon composition. Dual-phase (DP) steels are one of the important 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 DI-FORM grades exhibit low yield-to-tensile strength ratios and the name corresponds to the tensile strength. This datasheet provides information on forming. Filing Code: SA-563.
