Abstract

See full text

A method for producing a component made of a steel product coated with an Al—Si protective coating, includes:

    providing a substrate consisting of a steel produced coated with an Al—Si protective coating,heating the substrate to a temperature T1 such that the Al—Si protective coating is only partially pre-alloyed with Fe of the steel product,cooling the pre-alloyed substrate to room temperature,applying a corrosion protection oil to the surface of the pre-alloyed substrate, wherein the oil consists of a composition containing fatty acid ester,transporting the pre-alloyed substrate to which the oil has been applied,heating the pre-alloyed substrate to which the oil has been applied to a temperature T2 such that the Al—Si protective coating is fully alloyed with Fe of the steel product and the oil is removed without leaving residue, andshaping the re-heated substrate to form the component.
