  • Nickel-plated stainless steel sheet having excellent processability and manufacturing method thereof
    Patent number: 11898262
    Abstract: Nickel-plated stainless steel sheets and a method of manufacturing the same are provided. Each of the nickel-plated stainless steel sheets includes a stainless steel base plate and a nickel plating layer formed on at least one surface of the stainless steel base plate by electroplating, in which the nickel plating layer includes a strike plating layer and a main plating layer which are sequentially laminated on the one surface of the stainless steel base plate.
    Type: Grant

  • NICKEL-PLATED HEAT-TREATED STEEL SHEET HAVING EXCELLENT PROCESSABILITY AND METHOD OF MANUFACTURING THE SAME
    Publication number: 20230349062
    Abstract: A method of preparing a nickel-plated heat-treated steel sheet having excellent workability. The method includes the steps of forming a nickel layer by electroplating at least one surface of a base steel sheet with nickel (Ni); and forming a nickel-iron (Ni-Fe) alloy layer between the base steel sheet and the nickel layer through diffusion heat treatment of the base steel sheet and the nickel layer. The nickel-plated heat-treated steel sheet has a superficial Rockwell hardness of 52 to 62.

  • Manufacturing method of nickel plated steel sheet and nickel plated steel sheet prepared therefrom
    Patent number: 11802346
    Abstract: The present invention provides a nickel-plated and thermally-treated steel sheet with excellent corrosion resistance, in which a remaining nickel amount obtained by analyzing an nickel-iron alloy layer using energy dispersive spectrometry (EDS) or electron probe X-ray microanalysis (EPMA) after pure nickel remaining on the nickel-iron alloy layer was completely removed after the heat treatment for alloying of a nickel plated layer with base iron is 0.1 wt % or more to less than 30 wt % of the total amount of iron and nickel.
