Atmospheric corrosion-resistant steel, also known as weathering steel, is a low-alloy steel made by adding a certain amount of alloying elements to ordinary steel, the main alloying components are Cu, P, Cr, Ni and other elements.
Atmospheric corrosion resistant steel (i.e. weathering steel) is a low-alloy steel with good atmospheric corrosion resistance made by adding a certain amount of Cu, P, C or Ni, Mo, Nb, Ti and other alloying elements to the steel. In the industrial and rural atmospheric environment, weathering steel because of the formation of a dense and stable oxide protective film on the surface of its substrate, preventing the entry of corrosive media, has excellent resistance to atmospheric corrosion and other properties, while the rust layer formed by corrosion on the surface of plain carbon steel substrate is loose and micro-cracked, can not really play a role in the protection of the substrate steel.
