摘要： A method for producing a nitrided packaging steel from a hot-rolled steel product with a carbon content of 400 to 1200 ppm, utilizing a cold-rolling of the steel product to a flat steel product, subsequent recrystallization annealing of the cold-rolled flat steel product in an annealing furnace, in particular a continuous annealing furnace. A nitrogen-containing gas is supplied into the annealing furnace and is directed at the flat steel product to introduce unbonded nitrogen into the flat steel product in an amount corresponding to a concentration of more than 100 ppm, or to increase the amount of unbonded nitrogen in the flat steel product to a concentration of more than 100 ppm, and subsequent cooling of the recrystallized annealed flat steel product at a cooling rate of at least 100 K/s directly after the recrystallization annealing. Using this method, cold-rolled flat steel products may be produced for packaging purposes with a tensile strength of more than 650 MPa and in particular between 700 and 850 MPa.

摘要： A method for producing a steel sheet for packaging includes: cold-rolling a hot-rolled steel sheet made from a steel having a carbon content of 10 to 1000 ppm by weight, the steel of the hot-rolled steel sheet having a predetermined recrystallization temperature (TR); heating the cold-rolled steel sheet to a predetermined heating temperature (TE), where TR≤TE, the heating performed at least partially in the presence of a nitrogen donor at least until TR is reached such that when the cold-rolled steel sheet is heated, nitrogen from the nitrogen donor is diffused at least into a near-surface region of the cold-rolled sheet steel and incorporated in the near-surface region, as a result of which the TR in the near-surface region is increased by a value ΔT, where TE

摘要： The invention relates to sheet metal packaging products, in particular tinplate or electrolytically chrome-plated sheet steel (ECCS), consisting of a sheet steel substrate (S) with a thickness in the region of 0.1 mm to 0.6 mm and a coating (B), in particular made of tin and/or chromium or chromium and chromium oxide, that is electrolytically deposited on at least one side of the sheet metal substrate. In addition, at least one surface of the sheet metal packaging product provided with the coating (B) has a surface profile with periodically repeating structure elements in at least one direction, wherein an autocorrelation function resulting from the surface profile has a plurality of side lobes with a height of at least 20%, preferably at least 30% of the height of the main lobe. These sheet metal packaging products have improved and novel surface properties.

摘要： A method for producing a corrosion-resistant steel sheet made of an unalloyed or low-alloy and cold-rolled steel having a carbon content of less than 0.1 wt %. The method includes the following steps: applying a metal coating to the steel sheet; annealing the coated steel sheet in a recrystallizing manner by heating the coated steel sheet to temperatures in the recrystallization range by electromagnetic induction in an inert-gas atmosphere; and quenching the coated and annealed steel sheet. The metal coating is fused on during the recrystallization annealing.

摘要： The invention concerns a method for the production of an aluminized packaging steel from a cold-rolled steel sheet made of an unalloyed or low-alloy steel with the following steps: a. heating of the steel sheet by electromagnetic induction at temperatures in the recrystallization range of the steel at a heating rate of more than 75 K/s, so as to anneal the steel sheet in a recrystallizing manner; b. dipping of the steel sheet annealed in a recrystallizing manner into a molten aluminum bath, so as to apply an aluminum layer on the steel sheet, wherein the steel sheet, upon being dipped into the aluminum bath, has a temperature of at least 700° C.; and c. pulling the steel sheet out of the aluminum bath and cooling the aluminized steel sheet at a cooling rate of at least 100 K/s. The aluminized steel sheets are characterized by a high degree of strength and elongation at break and exhibit excellent formation characteristics, for example, in drawing and wall ironing processes, for the production of two-part food and beverage cans or lids and can be used as substitute material for tin sheets.
