  • Patent number: 10900110
    Abstract: A method for hot forming a steel component is provided. The steel component is heated into a range of complete or partial austenitization in a heat treatment step. The heated steel component is both hot-formed and quench-hardened in a forming step. A first pretreatment step precedes the heat treatment step in terms of process, in which first pretreatment step the steel component is provided with a corrosion-resistant protective layer in order to protect against scaling in the heat treatment step. Before the heat treatment step is performed, a surface oxidation process occurs in a second pre-treatment step, in which a weakly reactive, corrosion-resistant oxidation layer is formed on the scale protection layer by means of which oxidation layer abrasive tool wear is reduced in the forming step.

  • Patent number: 10808164
    Abstract: A method of inhibiting corrosion of duplex stainless steel by aqueous acidic solution, comprises carrying out a preliminary treatment which is passivation of the steel while exposing the steel to a first aqueous acidic solution containing at least one organic corrosion inhibitor able to adsorb to a steel surface, so as to deposit a passivating and corrosion inhibiting film on the steel surface; and thereafter during a second period of time exposing the steel to a second aqueous acidic solution different from the first aqueous acidic solution and also containing at least one organic corrosion inhibitor able to adsorb to a steel. The second aqueous acidic solution maintains the film on the steel surface, such that weight loss through corrosion in the second period of time is lower than the weight loss which would be observed with the same second aqueous acidic solution but without carrying out the preliminary treatment.
