EN10025-5 S355J0W is a structural steel plate with atmospheric corrosion resistance under the European standard, known as cotren steel plate (weathering steel plate). Its core advantage lies in its ability to form a stable oxide layer on its own in outdoor environments, significantly enhancing its rust resistance.
S355J0WP is a low-alloy high-strength weathering structural steel plate conforming to the European standard (EN 10025-5). It offers excellent atmospheric corrosion resistance and can be used outdoors for extended periods without painting.
EN10025-2 S355J0 is a high-strength structural steel with well-balanced comprehensive properties, offering cost-effectiveness. It is widely used in various structural and engineering applications due to its excellent strength, good toughness, and welding performance. When selecting, it is necessary to determine whether a higher grade with improved low-temperature toughness (such as S355J2 or S355K2) is required based on the minimum ambient temperature the structure will be exposed to.
S355J0W is a low-alloy, high-strength, weather-resistant structural steel in accordance with the EN 10025-5 standard. Its core weather resistance stems from the synergistic action of alloying elements such as Cu, Cr, Ni and other alloying elements, which work synergistically to form a dense, stable protective passivation layer (patina) on the surface in atmospheric environments. This effectively prevents further corrosion penetration, with atmospheric corrosion resistance 2–8 times that of ordinary carbon steel, allowing for long-term use in exposed conditions. The following provides an in-depth analysis covering several aspects, including chemical composition, mechanism of weather resistance, quantification of weather resistance, weathering performance in different environments, advantages of weathering resistance and limitations of use and application scenarios.
The welding procedure specification for S355J0W weathering steel includes the following: base metal properties, weldability analysis, pre-welding preparation, welding materials, welding parameters, key welding operations, post-welding treatment, welding quality inspection, and referenced standards.
