Chemical Composition of S235J2W Weathering Steel

S235J0W is a low-alloy weathering structural steel defined in the European standard EN 10025-5. Its key characteristic is that, through the synergistic action of alloying elements such as Cu, Cr, and Ni, it gradually forms a dense and stable protective rust layer in the atmosphere, thereby reducing the rate of further corrosion. The following are the main chemical compositions of S235J2W weathering steel and their primary functions.

Characteristics and Advantages of S235J2W Weathering Steel Plates

S235J2W is a weather-resistant structural steel plate manufactured in accordance with the EN 10025-5 standard, with the steel grade designation 1.8961. In this designation, “S235” represents the base yield strength class, “J2” indicates compliance with the impact toughness requirement at -20°C, and “W” indicates improved resistance to atmospheric corrosion.

S235J2W Weathering Steel Plate Technical Specifications

S235J2W is a structural steel resistant to atmospheric corrosion as defined in the European standard EN 10025-5, with the material designation 1.8961. It is characterized by the addition of alloying elements such as Cu, Cr, and Ni to the standard structural steel S235J2. After prolonged exposure to the atmosphere, a dense, stable patina forms on its surface, effectively isolating the steel from air and moisture erosion to enhance its corrosion resistance in atmospheric environments. It is widely used in outdoor steel structures, construction projects, bridge construction, municipal facilities, and railway engineering.
