摘要： A nitrided packaging steel in the form of a flat steel product and method for producing a nitrided packaging steel with a carbon content of 10-1000 ppm and uncombined nitrogen, dissolved in the steel, of more than 100 ppm. The nitriding is performed in two stages: a first stage, in which a molten steel is nitrided to a nitrogen content of at most 160 ppm by introducing a nitrogen-containing gas and/or a nitrogen-containing solid into the molten steel, and a second stage, in which a flat steel product produced from the nitrided molten steel by cold rolling is treated with a nitrogen-containing gas in order to increase further the amount of uncombined nitrogen in the flat steel product. The second stage is performed in an annealing furnace, in which the flat steel product is at the same time annealed in a recrystallizing manner. The packaging steels produced are distinguished by great strength, in excess of 600 MPa, and good elongation to fracture, regularly in excess of 5%, as well as by good forming properties.

摘要： A steel plate having a plated layer on the upper and lower surfaces thereof to be processed into a battery can which is cylindrical and open in one end thereof by drawing and ironing processing. The plated steel plate has more than 1.2 as a Lankford value (r) which is a width deformation degree in a lengthwise direction thereof/a thickness deformation degree in the lengthwise direction thereof, a width deformation degree in a widthwise direction thereof/a thickness deformation degree in the widthwise direction thereof, a width deformation degree in an oblique direction thereof/a thickness deformation degree in the oblique direction thereof. In-plane anisotropy .DELTA.r which is the difference among the Lankford values (r) is set to be less than .+-.0.15 so that the elongation coefficient of the plated steel plate in lengthwise, widthwise, and oblique directions is almost constant, i.e., so that the generation of earring can be prevented in drawing and ironing a sheet comprising the steel plate into the battery can. In order to make the elongation coefficient of the plated steel plate constant in the three directions, a very low carbon steel plate is used. The steel plate is cold-rolled at 80-90 %. The plated layer is allowed to have a granular structure by annealing it after it is plated.

摘要： A cold-rolled sheet is provided. The cold-rolled sheet includes a steel substrate with a carbon content C0 between 0.07% and 0.5%, expressed by weight, and a metal pre-coating on at least the two principal faces of the steel substrate. The substrate has a decarburized area on the surface of each of the two principal faces. The depth p50% of the decarburized area is between 6 and 30 micrometers, and p50% is the depth at which the carbon content is equal to 50% of the content C0. The sheet does not contain a layer of iron oxide between the substrate and the metal pre-coating.
