galvanized vs stainless steel rust

  • Stainless steel vs galvanized - WoodenBoat

    10/16/2010· Stainless steel is stain less not stain free. It depends on an oxide of chroimum layer on surface to keep it from corroding. In absence of oxygen the oxide layer breaks down and the surface loses it's passivation, and the area of passivation loss becomes anodic to other surfaces and starts corrosion, That corroded area is even lower on the galvanic chart and corrodes more readily.
