Document Type and Number:
WIPO Patent Application WO/2016/075866
Kind Code:
A1
Abstract:
Provided are a steel sheet to be used for cans and which has high strength and excellent moldability, and a manufacturing method for manufacturing the steel sheet for cans. The steel sheet for cans has: a component composition containing, in terms of mass%, C by 0.015%-0.150%, Si by 0.04% or less, Mn by 1.0%-2.0%, P by 0.025% or less, S by 0.015% or less, Al by 0.01%-0.10%, N by 0.0005% or more but less than 0.0050%, Ti by 0.003%-0.015%, and B by 0.0010%-0.0040%, and, as the remaining portion, Fe and unavoidable impurities; a steel sheet structure including a ferrite phase as a main phase and at least one of a martensitic phase and a residual austenitic phase as a second phase by 1.0% or more in terms of the total of area percentage; a tensile strength of 480 MPa or higher; a total elongation of 12% or higher; and a yield elongation of 2.0% or lower.
