  • Dissimilar Metals American Galvanizers Association

    Dec 10, 2017 · Zinc, which comprises the hot dip galvanized coating is very high on the Galvanic Series (Figure 2), which means it will be anodic to most other metals. So, when hot dip galvanizing is connected to other metals, the zinc coating will not only sacrifice itself to protect the underlying base steel, but also try to protect the other connected

  • Does hot dip galvanizing work for stainless steel?

    The hot dip galvanizing may not stick to the stainless steel unless the zinc penetrates the passive oxide film on the SS to form a metallurgical bond. HD galvanizing is typically not a good idea for 300 series SS because the zinc will preferentially penetrate the grain boundaries of the SS.
