What are the main characteristics and benefits of Weathering or Corrosion Resistant Steels?

Corten A and corten B Weathering steel,is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance Weathering means that due to their chemical compositions, these steels exhibit increased resistance to atmospheric corrosion compared to other steels.

Corten A, as the symbol of weathering steel material, weathering resistant steel or atmospheric corrosion resisting steel. Even, some people called all the weathering steel as Corten Steel.

Corten Bstarted from North America. Corten steel widely used in air preheater, economizer, railway carriage, containers production, bridge building , construction and so on.
