Raised flower beds tall concrete hortensia stand indoor self watering window wall flower pot planter boxes plant pots planters differ from other corrosion resistant steels, such as austenitic stainless steel, in resisting the formation of rust. Corten steel will rust, but the outer surface will only rust. Once the outer layer of rust is formed, the rust will not penetrate into the corten steel. The anti-rust layer on the surface acts as a barrier to prevent further corrosion of steel. In ordinary carbon steel, the rust layer formed is porous and will fall off, allows another layer to form deeper in the steel.
