Abstract: The present invention, among other things, relates to a method for producing a workpiece by press hardening a semi-finished product, which is distinguished by the fact that the semi-finished product consists of a steel which has a high content of silicon of at least 0.9 wt. %, with a simultaneously small content of manganese of less than 0.9 wt. %, a small carbon content of less than 0.25 wt. %, and a high chromium content of more than 1.20 wt. %, and which by heating is brought to a state in which the structure of the steel that is used is at least partially transformed to austenite, also optionally fully transformed to austenite, and the thus-heated semi-finished product is hot shaped so that after the hot deformation shaping, a structure is present in the workpiece that has a complex phase structure with predominantly martensite and ferrite fractions. In addition, a workpiece is described, which is produced according to this method, as well as uses of such a workpiece.

Abstract: A steel grade for use in a hot forming and press hardening process has the following composition, in weight percent: C 0.15%=C<0.35%, Mn 0.8-2.5%, Si 1.5-2.5%, Cr max. 0.4%, Al max. 0.1%, Ni max. 0.3%, B 0.0008-0.005%, Ti 0.005-0.1%, Nb max. 0.1%, remainder iron and unavoidable impurities as well as a hot formed and press hardened structural part made of this steel grade.

Abstract: The present invention relates to a coating material in the form of a suspension for the coating of metal surfaces of components prior to a thermal treatment for protection against corrosion. The coating material is hereby characterized in that the solid phase of the suspension primarily is composed of aluminum particles, and the liquid phase is composed of organic solvents and binders, the solid phase of the suspension containing at least two types of aluminum particle shapes, which are differentiated by their specific surface. In addition, a component is described, whose metal surface has been coated with a coating material according to the invention prior to thermal treatment and which has a contact resistance of <1 mOhm (DIN EN ISO 18594) after thermal treatment.
