Corten weathering steel is a type of low-alloy high-strength structural steel with good atmospheric corrosion resistance.
Chemical composition: Corten weathering steel usually contains carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), copper (Cu), chromium (Cr), nickel (Ni) and other elements, and the specific content varies depending on the model and standard. Generally speaking, the content of elements such as copper, chromium, and nickel is relatively high, which helps to improve its weather resistance.
Performance characteristics: Excellent atmospheric corrosion resistance: In the natural environment, a stable and dense rust layer will gradually form on its surface, which can prevent further corrosion and thus extend the service life of the steel.
High strength and good toughness: It has high yield strength and tensile strength, and has a certain toughness, which can meet the requirements of structural bearing.
Good welding performance: It can be connected and processed by conventional welding methods.
Application areas: Construction field: used for building exterior walls, roofs, bridges and other structures, giving the building a unique appearance and durability.
Transportation: Such as railway freight cars, containers, etc., can withstand harsh transportation environments.
Energy field: used in wind power towers, oil drilling platforms and other facilities.
