摘要： The invention relates to a method for producing a steel component that is coated with a metal protective coating from a sheet steel product comprising at least 0.4 wt % Mn. In order to economically generate a high-strength steel component, while minimizing the risk of the development of metal-induced cracks, according to the invention the sheet steel product is annealed in a continuous furnace under an annealing atmosphere containing up to 25% by volume H2, 0.1 - 10% by volume NH3, H2O, the remainder being N2 as well as process-related inevitable impurities, at a dew point ranging between -50ºC and -5ºC and at a holding temperature of 400 - 1100ºC for a holding period of 5 - 600 s. The annealed sheet steel product has a nitride layer (N) 5 - 200 pm thick, the particle size of which is finer than the particle size of the interior core layer (K) of the sheet steel product. After it has been coated with a metal protective layer, a blank is separated from the annealed sheet steel product and is soaked to an austenitizing temperature of 780 - 950ºC subsequent to an optional preforming step, hot-formed to form the steel component and cooled so quickly that a tempered martensitic structure forms in the sheet steel product.

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 rank hoard 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 Ar which is the difference among the rank hoard 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.
