EN 10155 is a European standard that specifies requirements for steels resistant to atmospheric corrosion. This steel grade is a structural steel with improved resistance to atmospheric corrosion. Under the EN 10155 standard, it includes a variety of steel grades, such as S355J0WP, S355J0W, S235J0W, S235J2W, etc.
The chemical composition of weathering steel under the EN 10155 standard has strict requirements and mainly includes a variety of elements. For example, the content of carbon (C) should not exceed 0.16%, the content of silicon (Si) should not exceed 0.50%, and the content of manganese (Mn) should be between 0.50% and 1.50%. In addition, the content of phosphorus (P) and sulfur (S) should not exceed 0.035%. For alloying elements, the content of chromium (Cr) should be between 0.30% and 1.25%, the content of nickel (Ni) should not exceed 0.65%, the content of copper (Cu) should be between 0.25% and 0.55%, and the content of vanadium ( The content of V) should be between 0.02% and 0.10%, while the content of titanium (Ti) should not exceed 0.12%.
The production methods of EN 10155 atmospheric corrosion-resistant steel mainly include smelting, continuous casting, rolling and other processes. In the smelting stage, by controlling the composition of raw materials and the smelting process, it is ensured that the steel has the required chemical composition and properties. The continuous casting process ensures the purity of the steel and the uniformity of the structural structure. The rolling process gives the steel the desired shape and size.
The characteristics of EN 10155 are mainly reflected in its resistance to atmospheric corrosion. This steel has improved resistance to atmospheric corrosion, allowing it to maintain its structural and performance stability over long periods of time in outdoor environments. Its chemical composition and mechanical properties are carefully designed to meet the needs of different application scenarios.
EN 10155 has a wide range of applications. Used in the construction of vessels that can withstand low-temperature seawater and in riveted, bolted or welded structures of pidges and buildings. Gas corrosion performance and wide applicability play an important role in many fields.
