S235J0W is a low-alloy structural steel resistant to atmospheric corrosion as defined in the European standard EN 10025-5, with the material designation 1.8958. 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.
S355K2W is a high-strength, weather-resistant structural steel specified in the European standard EN 10025-5, with the steel grade designation 1.8967. This steel grade combines a yield strength of approximately 355 MPa with good low-temperature impact toughness and weather resistance, and is commonly used in bridges, building steel structures, towers, and structural components subject to long-term exposure to the atmosphere.
S355J2WP is a weathering steel conforming to the European standard EN 10025-5 (commonly known as Corten steel). Its primary equivalent materials are listed below.
S355J2WP is a low-alloy weather-resistant structural steel plate that complies with the EN 10025-5 standard. After prolonged exposure to the atmosphere, a dense, stable protective rust layer (patina) forms on its surface, effectively blocking corrosion caused by air and moisture. It combines high structural strength, excellent low-temperature toughness, and good weather resistance, and is widely used in outdoor steel structures, construction projects, bridge construction, municipal facilities, and railway engineering. The main chemical composition requirements for S355J2WP weathering steel plates are as follows.
S355J2WP is a weather-resistant structural steel specified in the European standard EN 10025-5. It features unique self-protective weather resistance, stable low-temperature toughness, excellent workability, and an exceptionally long service life, making it suitable for the construction of outdoor steel structures. S355J2WP weather-resistant steel plates address the core challenges faced in outdoor steel structure projects, including rapid atmospheric corrosion, short structural service life, high maintenance costs, and poor structural stability at low temperatures.
