S235J2W weathering steel plate

S235J2W weathering steel plate is a steel with improved atmospheric corrosion resistance, which complies with European standard EN 10025-5. This steel contains specific alloy components, such as copper and nickel, which can improve its corrosion resistance. The weathering resistance of S235J2W is 2 to 8 times that of ordinary carbon steel, and the paintability is 1.5 to 10 times that of ordinary carbon steel. It can be used to manufacture steel structures such as vehicles, bridges, towers, containers, etc.

Product Details

S235J2W is a European standard weathering steel plate with good atmospheric corrosion resistance.
Implementation standard: EN10025-5
Chemical composition (melting analysis,%): C≤0.16, Si≤0.45, Mn is 0.2-0.6, P≤0.035, S≤0.03, Cr is 0.4-0.8, Cu is 0.25-0.55, Ni≤0.7.
Features: By adding a certain amount of copper (Cu), phosphorus (P), chromium (Cr), nickel (Ni) and other alloy elements to the steel, a dense and stable oxide protective film is formed on the surface of the substrate, which can effectively hinder the entry of corrosive media, thus having excellent atmospheric corrosion resistance. In industrial and rural atmospheric environments, the weather resistance of this steel plate is 2-8 times that of ordinary carbon steel.
Application areas: It is often used to manufacture steel structures exposed to the atmospheric environment for a long time, such as bridges, railway vehicles, pillars and load-bearing beams of industrial and civil buildings, various alloy structures and their components, structural parts of various engineering machinery, hulls, offshore oil platforms, platform pipe joints and other structural parts. It can also be used to make various structural parts that work in the atmospheric environment and corrosive gases and liquids.
