\"corten<\/p>\n

Weathering steel, often referred to by the genericized trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys that were developed to eliminate the need for painting and form a stable rust-like appearance after several years’ exposure to weather.<\/p>\n

The surface oxidation of weathering steel takes six months, but surface treatments can accelerate the oxidation of corten steel to as little as one hour.<\/p>\n

ASTM A242 is available in Type 1 and Type 2. Both have different applications based on the thickness. Type 1 is often used in housing structures, the construction industry, and freight cars. Type 2 steel, which is also called Corten B, is used primarily in urban furnishing, passenger ships, or cranes.<\/p>\n\n\n\n\n\n

A588 is available in steel plate and starts at 3\/16\u201d thickness and increases up to 5\u201d thickness. A588 is a high strength low alloy plate used for structural applications such as buildings and bridges.<\/p>\n
