Abstract

A steel sheet for crown cap having excellent formability from which a crown cap having an excellent pressure resistance can be produced without an expensive soft liner even if the steel sheet is subjected to sheet metal thinning, the steel sheet having: a chemical composition containing, in mass %, C: more than 0.006% and 0.012% or less, Si: 0.02% or less, Mn: 0.10% or more and 0.60% or less, P: 0.020% or less, S: 0.020% or less, Al: 0.01% or more and 0.07% or less, and N: 0.0080% or more and 0.0200% or less, with the balance being Fe and inevitable impurities; and a percentage of a region of more than 0% and less than 20% at a position of ½ of a sheet thickness, the region having a dislocation density of 1×10¹⁴ m⁻² or less.
