Introduction To Atmospheric Corrosion Resistant Steel

Atmospheric corrosion-resistant steel, also known as weather-resistant 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.
Basic Information
Atmospheric corrosion-resistant steel (i.e. weather-resistant steel) refers to 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 industrial and rural atmospheric environments, weathering steel forms a dense and stable oxidation protective film on the surface of its substrate, which blocks the entry of corrosive media and has excellent resistance to atmospheric corrosion. However, the surface corrosion of ordinary carbon steel forms The rust layer structure is loose and has micro-cracks, which cannot truly protect the base steel.
