Technical Specifications for S235J0W Weathering Steel Plate

S235J0W is a low-alloy structural steel resistant to atmospheric corrosion, designated as grade 1.8958 in the European standard EN 10025-5. It is characterized by the addition of alloying elements such as Cu, Cr, and Ni to standard structural steel, which imparts superior atmospheric weathering resistance and enables the formation of a stable protective rust layer. EN 10025-5:2019 specifies the technical delivery conditions for its hot-rolled flat products and long products.
