Abstract
A silicon-containing high strength steel sheet having isotropic high ductility and toughness in all directions independently of the rolling direction comprising 0.03 to 0.15% C, 0.7 to 2.3% Si, 0.7 to 2.0% Mn with the balance being iron and unavoidable impurities, in which the ratio of Si/Mn is between 0.6 and 1.5 and the content of S is maintained in an amount as low as possible below that normally contained as an unavoidable impurity.
