The Impact of Nickel Content in Steel Tubes and Galvanizing Pot Substrates on Hot-Dip Galvanizing

Nickel (Ni) is gray in color, belonging to either the cubic or hexagonal crystal system, with a relative atomic mass of 58.69, a melting point of 1455°C, and a boiling point of approximately 2340°C. The influence of nickel on hot-dip galvanizing varies among scholars due to differences in experimental methods. Some believe that when comparing low-carbon steel without nickel to low-carbon steel with 5% nickel at a zinc bath temperature of 460°C, the corrosion rate of the latter is reduced by 30% compared to the former. When the nickel content in steel reaches 8%, the thickness of the galvanized layer decreases, indicating that nickel controls the development of the ζ-phase in this context.
