Abstract (en)

[origin: WO2005068667A1] In the manufacturing method of steel sheets for use in containers, steel (which may contain less than or equal to 0.0800% C, 0.600% N, 2.0% Si, 2.0% Mn;, 0.10% P, 0.05% S, 2.0% Al and residual amounts of Fe), after cold-rolling, may undergo a recrystallization annealing process. By adjusting the environment, temperature and duration of the heat treatment which follows, it is possible to control the area ratio of nitrides on the surface to be greater than or equal to 1.0%. Furthermore, it is possible to control the greater of the density of the individual nitrified area of 0.1 µm or greater and the individual steel base material to be greater than or equal to 0.001 units/µm<2>.
