Abstract :

Forta H, Outokumpu has developed a special material exclusively for automotive applications. This material combines good formability with high strength, where the strength increases further during the forming process. These properties enable new lightweight concepts. The alloy design of the new lightweight material is based on an austenitic microstructure. During forming, this austenitic structure provides the formation of so-called â�?�?twinsâ�? and thus to increase the strength of the material enormously. Hence, the good formability can be ideally combined with a high strength. Traditional materials such as aluminum or carbon steels do not show this effect. The material is called â�?�?Forta Hâ�? and is industrially available. The base material â�?�?Forta H500â�?, named after its yield strength, has a tensile strength of over 900 MPa with an elongation after fracture of more than 50%. By hardening, the grades â�?�?Forta H800â�? and â�?�?Forta H1000â�? can be achieved. The strengths of this special material increase during the forming process and in case of a crash. The material, developed for automotive applications, is widely tested and available on an industrial scale. It is offered in sheet thicknesses of t=0.5 mm to t=4.0 mm and a width up to b=1350 mm, where additional dimensions are conceivable. The presentation will provide an overview of the features and benefits of the new ultra-high- strength grades of Outokumpu. In this regard, a variety of results, such as weldability, formability, fatigue behavior, and corrosion resistance will be shown. Finally, some applications will be presented.
