Document Type and Number:
WIPO Patent Application WO/2021/177231
Kind Code:
A1
Abstract:
A Ni-plated steel sheet according to one embodiment of the present invention comprises a base steel sheet and a Ni-plated layer provided to a surface of the base steel sheet. The Ni-plated layer includes a Ni-Fe alloy layer formed on the surface of the base steel sheet. The ratio of Zn content to the Ni content in the Ni-plated layer is 0.0005-0.10%. A Ni-plated steel sheet manufacturing method according to one embodiment of the present invention includes: a step for obtaining a raw material Ni-plated steel sheet by electroplating the base steel sheet using a Ni-plating bath where [Zn2+]/[Ni2+] is 0.0005-0.10%; and a step for annealing the raw material Ni-plated steel sheet.
