Abstract (en)
[origin: EP3916112A1] An object is to provide a steel plate having excellent deformability in the central portion in the thickness direction and a method for manufacturing the steel plate.A steel plate having a chemical composition containing, by mass%, C: 0.01% to 0.15%, Si: 0.01% to 1.00%, Mn: 0.10% to 2.00%, P: 0.010% or less, S: 0.0050% or less, Al: 0.002% to 0.100%, Ni: 5.0% to 10.0%, N: 0.0010% to 0.0080%, and with a balance being Fe and incidental impurities and a percentage reduction of area of 30% or more in a tensile test in the thickness direction performed on the central portion in the thickness direction.
