Abstract
Coating steel strips comprising, in % by weight, C: ≦1.6%, Mn: 6-30%, Al: ≦10%, Ni: ≦10%, Cr: ≦10%, Si: ≦8%, Cu: ≦3%, Nb: ≦0.6%, Ti: ≦0.3%, V: ≦0.3%, P: ≦0.1%, B: ≦0.01%, the rest being iron and unavoidable impurities, and a method of forming steel strips are described. Up to now, such steel strips were not adequately coatable, with a metal coating ensuring outstanding corrosion-resistance and good welding properties. This is ensured by applying an aluminium layer to the steel strip before final annealing and applying the metal coating to said aluminium layer after final annealing.
