EN 10025 - 5 S420K2W Corten Steel
The "S" represents structural steel, "420" indicates that its minimum yield strength is 420MPa, which can bear heavy loads. "K2" means that the steel has good impact resistance at a low temperature of - 25℃, and "W" shows that it has excellent weather - resistance. This steel is added with trace alloy elements such as copper, chromium and phosphorus. It can form a dense and adherent rust - proof protective film on the surface in the atmosphere, which can effectively prevent further corrosion, just like wearing a "protective coat" for itself.
