Hot rolled corten steel weathering steel Grade 09CuPCrNi SPA-H
"Weathering" refers to the chemical composition of these steels, allowing them to exhibit increased resistance to atmospheric corrosion compared to other steels. This is because the steel forms a protective layer on its surface under the influence of the weather.
The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words, the steel is allowed to rust in order to form the 'protective' coating.
Weathering steel is popularly used in outdoor sculptures, bridge and other large structural applications, construction of intermodal containers as well as visible sheet piling.
