Abstract (en)
[origin: EP1065286A1] Annealing of the steel strip comprises heating to a temperature above that of the onset of perlitic transformation Ac1, holding the temperature above this temperature for more than 10 s, rapid cooling to below 100 degrees C, at a rate exceeding 100 degrees C/s, low temperature treatment at 100 degrees C-300 degrees C for more than 10 s, and cooling to ambient temperature. Production of a low aluminum steel strip for manufacture of containers comprises: (a) providing a hot-rolled steel strip containing in (wt.%): 0.050-0.080 C; 0.25-0.40 Mn, 0.020 Al, 0.010-0.014 N, and the remainder iron and inevitable impurities; (b) primary cold rolling the strip; (c) annealing the cold rolled strip; and (d) secondary cold rolling. An Independent claim is included for steel strip of the above-specified composition which satisfies an equation relating ultimate elongation and ultimate tensile strength.
