Stainless Steel in Contact with Galvanized Steel

Oct 05, 1999 · The zinc has been applied to the steel to provide corrosion protection for the underlying base steel. If zinc is in contact on the surface with a more cathodic metal and the zinc becomes part of a bimetallic couple and corrodes, then the zinc is not performing its designed function of protecting the base steel.

HOT DIP GALVANIZED AK Steel

HOT DIP GALVANIZED STEEL, known as ZINCGRIP® Steel, is continuously coated on both sides with a zinc coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc.

3 Safety Concerns when Welding Galvanized Steel

Galvanized refers to the coating of zinc on to steel. Zinc oxidizes to protect the steel near it which means, even if the galvanized steel surface is removed due to scrapping or scratching down to the bare steel, the galvanized coating will prevent rust from occurring. 1. Metal Fume Fever. When welding galvanized steel the zinc coating vaporizes and mixes with the air to form zinc oxide fumes.
