Products Description
S355K2G1W High Strength Low Alloy Corten Steel Plate is a weathering steel under the EN 10155 standard, also known as weathering steel. It is a low-alloy steel produced by adding specific proportions of alloying elements (such as Cu, P, Cr, Ni) to ordinary carbon steel.
The defining characteristic of weathering steel is its ability to form a stable protective oxide layer in natural atmospheric environments, effectively resisting corrosion and extending its service life to typically 4–8 times that of ordinary carbon steel.
Compared to stainless steel, S355K2G1W weathering steel plate contains only trace amounts of alloying elements (P, Cu, Cr, Mo, Nb, V, Ti, etc., totaling just a few percent), whereas stainless steel may contain over ten percent alloying elements, making it a more economical choice.
In terms of mechanical properties, S355K2G1W corten steelplate demonstrates stable and reliable performance: yield strength ≥355 MPa (for thickness ≤16 mm), tensile strength 470–630 MPa, elongation ≥20%, impact toughness at -20°C ≥27 J, and a density of approximately 7.85 g/cm³.
These properties enable outstanding performance in applications demanding high strength and weather resistance, such as bridges, building structures, storage tanks, vehicles, and mining equipment.
Combining high strength, excellent corrosion resistance, and cost-effectiveness, S355K2G1W high strength corten steel plate stands as a highly cost-efficient choice in the weathering steel market.
