Document Type and Number:
WIPO Patent Application WO/2018/198835
Kind Code:
A1
Abstract:
Provided are: a material for a cold-rolled stainless steel sheet, said material being suitable for producing a cold-rolled ferritic stainless steel sheet exhibiting excellent corrosion resistance and excellent mouldability and ridging resistance; and a production method therefor. This material for a cold-rolled stainless steel sheet is provided with a component composition which includes, in mass%, 0.005-0.030% of C, 0.05-1.00% of Si, 0.05-1.00% of Mn, 0.040% or less of P, 0.030% or less of S, 0.001-0.150% of Al, 10.8-14.4% of Cr, 0.01-2.50% of Ni, and 0.005-0.060% of N, the remainder comprising Fe and unavoidable impurities. The material for the cold-rolled stainless steel sheet is provided with a structure which includes, in area ratio, 10-90% of martensite phase, the remainder comprising ferrite phase.
