Weathering steel is a kind of alloy steel, which can form a relatively dense rust layer on the surface after several years of outdoor exposure, so it does not need to be painted for protection. Weathering steel is best known as "COR-TEN", which is abbreviated as "Corrosion resistance" (corrosion resistance) and "Tensile strength" (tensile strength), so it is often referred to as "Corten Steel" in English. Different stainless steels can be completely rust-free, and weathering steels are only oxidized on the surface and will not penetrate deep into the interior, and have anti-corrosion characteristics like copper or aluminum.
The weather resistance of weathering steel is due to the specially designed chemical composition and chemical composition distribution, so that it can form a protective layer on the surface of the material under the influence of environmental weather, and is more corrosion and weather resistant than most steel grades (such as stainless steel).
The specially designed distribution of alloying elements in the weathering steel provides a protective layer, which in turn produces a corrosion-inhibiting effect. The protective layer on the surface of weathering steel will slowly grow and regenerate with the influence of weather. In short, this steel grade is formed by the surface scale to form a protective layer.
A588 Alloy has a yield strength of 50 kpsi (340 MPa) and an ultimate tensile strength of 70 k for all rolled sections and sheets up to 4 in. (100 mm) thick pounds per square inch (480 megapascals). Sheets in the thickness range of 4 to 5 inches (100 to 130 mm) have a yield strength of at least 46 thousand pounds per square inch (320 MPa) and an ultimate tensile strength of at least 67 thousand pounds per square inch (460 MPa). megapascals). Sheets with a thickness of 5-8 inches (127-203 mm) shall have a yield strength of at least 42 thousand pounds per square inch (290 MPa) and an ultimate tensile strength of at least 63 thousand pounds per square inch (430 MPa). megapascals).
The alloying elements such as chromium and nickel used in weathering steel are less than those of stainless steel, and the price is usually cheaper than that of stainless steel. At some point, weathering steel is a corrosion-resistant and economical alternative to stainless steel.
