Abstract
A method for producing a steel component from a flat steel sheet is provided. The produced steel component includes a substrate and a coating. The method ensures that the steel component has an Hcontent below a certain level. The low Hcontent minimizes the risk of hydrogen-induced cracking of the steel component after hot forming, including during subsequent use of the steel component. The Hcontent in the hot-formed steel component is ensured to be below a certain level by selecting furnace parameters depending on the rolling degree and the sheet thickness of the flat steel sheet.
