Method of producing high-strength steel sheet used for can.

摘要

A method of producing a steel sheet useful for making cans. The method steps include hot-rolling a slab consisting of about 0.0005 to 0.01 wt% C, about 0.001 to 0.04 wt% N (the total of C and N is at least about 0.008 wt%), about 0.05 to 2.0 wt% Mn, about 0.005 wt% or less Al, about 0.01 wt% or less O at a finish rolling temperature within a temperature range of about the Ar3 point to about 950 DEG C, coiling the rolled material at a temperature range of about 400 to 600 DEG C, cold rolling the material, continuously annealing the material at a temperature higher than the recrystallization temperature, and then temper-rolling the material. The steel sheet exhibits good workability during can making and which can be formed into a can having high strength. <IMAGE>
