摘要： A flat steel product for hot forming may be produced from a steel substrate that includes a steel comprising 0.1-3% by weight Mn and up to 0.01% by weight B, along with a protective coating that is applied to the steel substrate. The protective coating may be based on Al and may contain up to 20% by weight of other alloy elements. Also disclosed are methods for producing such flat steel products, steel components, and methods for producing steel components. Absorption of hydrogen is minimized during heating necessary for hot forming. This is achieved at least in part through an alloy constituent of 0.1-0.5% by weight of at least one alkaline earth or transition metal in the protective coating, wherein an oxide of the alkaline earth or transition metal is formed on an outer surface of the protective coating during hot forming of the flat steel product.

摘要： The invention relates to a method for producing a steel component by forming of a flat steel product coated with an anticorrosion coating, and to a steel component produced from a steel substrate coated with anticorrosion coating. The steel component is produced by providing a flat steel product coated with an aluminum-based anticorrosion coating, heat-treating a blank formed from the coated flat steel product, in a furnace, where 0.0034° C./min≤Q≤0.021° C./min, with Q=(T*d)/(t*L), T=furnace temperature in ° C., d=blank thickness in mm, t=dwell time of the blank in the furnace in min, L=furnace length in m, and shaping the blank in a shaping tool. The steel component comprises a steel substrate and, at least on one side of the steel substrate, an anticorrosion coating which comprises at least one first and one second silicon-rich layer (Si1, Si2) and also one first and one second low-silicon layer (A, B), where the quotient X formed from the thickness (dB) of the second low-silicon layer (B) in μm by the thickness (dA) of the first low-silicon layer (A) in μm is at least 0.4 and at most 1.1.

摘要： Certain methods enable the production of steel components with well-adhering metallic coatings that protect against corrosion. In some examples, a flat steel product produced from a steel material having a yield point of 150-1100 MPa and a tensile strength of 300-1200 MPa may be coated with an anticorrosion coating of an alloy that comprises 35-70% by weight aluminum, 35-60% by weight zinc, 0.1-10% by weight magnesium, up to 10% by weight Si, and up to 5% by weight Fe. A blank obtained from the flat steel product may then be heated to at least 800° C. and formed into a steel component. Alternatively, the steel component may be formed into the steel component first and then heated to at least 800° C. Regardless, the steel component may then be hardened by sufficiently rapid cooling the steel component from a sufficiently high temperature.
