Abstract

To provide a steel sheet for crown caps, having sufficient pressure resistance and formability regardless of gauge reduction; a method for manufacturing the same; and a crown cap. A steel sheet for crown caps has a predetermined composition, wherein N total-(N as AlN) is 0.0090 pcnt to 0.0170 pcnt , the maximum grain size of a carbide is 2.0 æm or less in a cross section in a rolling direction, and the yield strength is 420 MPa to 600 MPa in the rolling direction. A method for manufacturing a steel sheet for crown caps includes a hot rolling step of coiling a steel material having a predetermined composition at a predetermined temperature after finish rolling; a primary cold rolling step; a continuous annealing step of performing heating at an average heating rate of 10 øC/s to 30 øC/s in a temperature range A from 500 øC to 600 øC in a heating course, annealing at a annealing temperature B in a temperature range from 620 øC to 740 øC, cooling from the annealing temperature B to a cooling stop temperature C in a temperature range from 400 øC to 580 øC at an average cooling rate of 20 øC/s or more, and retaining in the temperature range from 400 øC to 580 øC for a retention time of 30 seconds to 90 seconds after cooling at the above average cooling rate is stopped; and a secondary cold rolling step of performing cold rolling at a rolling reduction ratio of 1.0 pcnt to 12 pcnt .
