Application Summary AI generated
GB/T 4171-2008 specifies the technical requirements for atmospheric corrosion resisting structural steel, commonly known as weathering steel. It is applied in the manufacturing of bridges, railway vehicles, containers, and building structures that are exposed to outdoor environments, where enhanced resistance to atmospheric corrosion reduces maintenance needs. The standard defines chemical composition, mechanical properties, and delivery conditions for steel plates, strips, and sections used in these long-term outdoor applications.
