A34 - Indaten® atmospheric corrosion resistant steels When used uncoated and exposed to bad weather, a protective oxide layer develops on the steel surface. That is why this steel is often called “the weathering steel”. Advantages With their characteristic colour, Indaten® 355 steels are used in architectural projects either to harmonise with the environment or to create a pleasing contrast with other materials, such as stainless steel. When used uncoated and exposed to bad weather, an oxide layer develops on the steel surface, forming a purplish-brown, finely grained patina that bonds very strongly to the steel and protects it. If the patina is damaged, the steel re-oxidises, thus repairing the patina and maintaining the protective barrier. Indaten® 355 can also be coated (paint, metallic coatings etc). In the case of coated parts, the protective layer prevents rust propagation under the paint layer. Experience has shown that the adhesion of organic coatings on Indaten® 355 is superior to bonding on other carbon steel grades. Applications Indaten® 355 has a wide range of applications: architecture, sculpture, engineering structures, smokestacks, freight wagons, silos, containers and pylons. When used uncoated, no maintenance is required and the material will not deteriorate through corrosion. The effectiveness of the corrosion protection largely depends on the speed of patina formation. For optimum patina formation, Indaten® 355 can be used in a non-confined environment, even in the presence of sulphuric fumes. However, it is strongly recommended not to expose Indaten® 355 to condensation or repeated soiling, particularly in environments containing free chlorine.
