  • Galvannealed steel sheet
    Patent number: 12378627
    Abstract: A galvannealed steel sheet obtainable by a method including the provision of a specific steel sheet, a recrystallization annealing with specific heating, soaking and cooling sub-steps using an inert gas, a hot-dip galvanizing and an alloying treatment, wherein the zinc coating is alloyed through diffusion of the iron from the steel sheet such that the zinc coating includes from 5 to 15% by weight of Fe, oxides including FeO, Mn2SiO4 and MnO, the balance being zinc, the steel sheet including internal oxides including FeO, Mn2SiO4 and MnO in the steel sheet.
