The present invention relates to a method for the manufacture of galvannealed metal sheet, wherein a hot strip is produced from an IF steel containing 0.01 to 0.1 wt. % silicon, wherein the hot strip is coiled at a coiler temperature no lower than 700° C. and no higher than 750° C., wherein a cold strip is rolled from the coiled hot strip, wherein the cold strip is recrystallisation-annealed in an annealing furnace in an annealing gas atmosphere, wherein the cold strip thus annealed is provided with a zinc coating in a zinc bath, and wherein the coated cold strip is post-annealed at a galvannealing temperature no lower than 500° C. and no higher than 540° C. The invention also relates to a galvannealed metal sheet which possesses improved adhesion of the coating layer to the base material and proposes a method which is suited for the manufacture of metal sheet having such properties.

The present invention relates to a method for producing electroplating annealed thin sheets wherein a hot-rolled strip is produced from IF steel (solid solution interstitial element free steel) containing 0.01-0.1 weight % of silicon. Said hot-rolled strip is coiled at a coiling temperature not less than 700 °C and not more than 750 °C. A cold-rolled strip is rolled from said hot-rolled strip, coiled and annealed up to recrystallization in an annealing furnace, in a hot gas atmosphere. Thus annealed cold-rolled strip is coated with a zinc coat in a zinc bath then reannealed at an electroplating temperature not less than 500 °C and not more than 540 °C. The present invention further relates to an electroplating annealed thin sheet with a coating layer having better adhesion on the base material, as well as a method adapted to thin sheet production according to said invention.
