Weathering Steel – Use and Preparation When Left Uncoated and When Coated. Weathering steel, often referred to by the genericized trademark COR-TEN steel, is a group of steel alloys developed to form a stable corrosion-resistant surface after several years exposure to weather, potentially eliminating the need for painting in many environments.
Corten Steel (sometimes known as weathered steel) is a group of steel alloys that are often used in outdoor construction. Corten Steel was designed to eliminate the need for painting and if left outside, exposed to the elements, they will develop a rusted appearance in just a few months.
Weathering steel, is atmospheric corrosion resistance steel, also known by corten steel. It is the material that between normal carbon steel and stainless steel and with low alloy content. So corten steel is the carbon steel that added with copper (low Cu), Chrome (low Cr) elements, these elements exist to bring anti-corrosion performances.
The ASTM specifications are A588, A242, A606-4, A847, A871-65 and A709-50W. The primary trademarked product is Cor-ten®. The selection of a particular ASTM weathering steel specification is dependent on the type of product desired. ASTM A588 covers structural shapes, plate, and bar. ASTM A242 covers steel plate through one-half inch in thickness.
Jul 20, 2019 · 1. Introduction. Weathering steels (WS), often referred to as low-alloy steels, are steels with low carbon contents and low to medium additions of one or several other alloying elements (Cu, Cr, Ni, P, etc.) to a total alloying content of at least 1.00 wt% and no more than 5.00 wt%, a higher proportion than is normally encountered in mild steels.
Weathering steel is an alloy formulation that forms a tight patina of rust on its surface with exposure to the environment. The patina seals the interior of the steel member and protects it against any further corrosion. The contemporary designation used for weathering steel used in highway bridges is A709W.
Weathering Steel: A Guide to Corten and the A/B Equivalents, Origins & Standards. Weathering steel (WS), also known as low‐alloy steel, are steels with a carbon content of less than 0.2 wt. % to which mainly Cu, Cr, Ni, P, Si and Mn are added as alloying elements to a total of no more than 3‐5 wt. % [1]. The chemical composition of these ...
