Continuous Hot‐Dip Galvanizing of Medium‐Manganese Third‐Generation Advanced High‐Strength Steels
steel research international, Volume 94, Issue 11, November 2023., 2023 Herein, the effects of process atmosphere pO2 on the reactive wetting of two medium‐Mn third‐generation advanced high‐strength steels during continuous hot‐dip galvanizing are interrogated. The substrates are austenitized, flash‐pickled, intercritically annealed, and galvanized in a conventional 0.2 wt% Al (dissolved) bath.
