Document Type and Number:
WIPO Patent Application WO/2019/021909
Kind Code:
A1
Abstract:
Provided are: a steel sheet for battery outer tube cans, which is used for an aftergilding method and is suppressed in the occurrence of scratches even in cases where press molding is repeated with use of a mold that is formed from a quenched steel, and which enables the achievement of a battery outer tube can that has excellent corrosion resistance and buckling resistance; and a battery outer tube can and a battery, each of which uses this steel sheet for battery outer tube cans.
This steel sheet for battery outer tube cans has an Fe-Ni diffusion layer on both surface layers of a steel sheet; the Nb content in the steel sheet is from 0.010% by mass to 0.050% by mass (inclusive); and the adhesion amount of the Fe-Ni diffusion layer per one surface of the steel sheet is from 50 mg/m2 to 500 mg/m2 (inclusive) in terms of Ni.
