Ferrite-bainite steels - ArcelorMittal

This range of hot-rolled high-strength steels has been developed to meet weight -reduction requirements.This family of steels extends the HSLA range of micro-alloyed steels to include products combining high tensile strength (UTS) with excellent aptitude for forming and stamping (stretch-flangeability) based on their ferritic-bainitic microstructure.Dual Phase steelsDual Phase steels offer a good combination of strength and stampability as a result of their microstructure,in which a hard martensitic or bainitic phase is dispersed in a ductile ferritic matrix.These steels have high strain hardenability.This gives them not only good strain redistribution capability and thus stampability,but also finished part mechanical properties,including yield Dual Phase Steels - ArcelorMittalHDGA Hot-Dip-Galvannealed Yes Products Commercially Available 'DEV' products are under development or in limited production.Please inquire about the status and availability of these products.ArcelorMittal produces two types of dual phase steel.The DI-FORM grades are conventional DP steels with low yield-to-tensile-strength ratios.
