Is galvanized steel magnetic?


Quick Answer

Galvanized steel is magnetic. Even though the galvanization process involves coating the steel with zinc, a nonmagnetic metal, the magnetic properties of the steel are not hindered by the zinc coating.

Full Answer

Steel is an alloy of iron and carbon, which makes it ferromagnetic due to its high iron content. Galvanized steel is made by dipping steel into molten zinc. This creates a thin protective coating that prevents corrosive materials from making direct contact with the more sensitive steel. Stainless steel that is made only with steel combined with chromium and nickel also has magnetic properties. Austentic steel is nonmagentic. This is due to the high temperatures involved in austenitization that result in the crystal structure of the iron component of steel being changed from ferrite to austenite.
