Abstract: Producing a hardened steel product can comprise providing a steel substrate of a hardenable steel; coating the steel substrate with an aluminum precoating, wherein the precoating is applied to the steel substrate with a thickness of at least 34 ?m; flexible rolling the pre-coated steel substrate to produce a variable thickness along the length of the precoated steel substrate, wherein the precoating is rolled out to a reduced first thickness of less than 33 ?m in thinner first portions and to a reduced second thickness thicker than the reduced first thickness in thicker second portions; working out a blank from the flexibly rolled steel substrate; heating the blank to austenitizing temperature, wherein diffusion processes take place between the base material and the precoating; and hot forming the heated blank, wherein the heated blank is formed and rapidly cooled such that a hardened steel product with coating is produced.

Abstract: A product is made from a rolled strip material with the steps: rolling of a strip material from a sheet metal; working of a blank out of the rolled strip material; forming of the blank to a formed part; cleaning the formed part such that an amount of maximal 0.7 ppm of diffusible hydrogen is introduced into the formed part by cleaning, and coating the formed part with a metal coating material for producing a corrosion protection coating, wherein the step of coating is carried out in an immersion bath with an electrolyte solution, wherein between the formed part and the electrolyte solution a flow is generated.
