Corten steel, also known as weathering steel, is a type of steel alloy that contains increased levels of copper, chromium, and nickel compared to other types of steel. This alloy is designed to form a protective layer of rust-like material when exposed to atmospheric elements, which helps to protect the steel from corrosion and extend its lifespan.
The ASTM A242 and A588 grades of Corten steel are two of the most commonly used grades for outdoor applications. These grades are specifically designed to resist atmospheric corrosion and to provide longer service life for structures and buildings exposed to the elements.
The ASTM A242 grade of Corten steel is a high-strength, low-alloy steel with improved atmospheric corrosion resistance. It has a yield strength of 50,000 psi (345 MPa) and a tensile strength of 70,000 psi (480 MPa). Its composition includes copper, nickel, chromium, and phosphorus. The A242 grade is commonly used for outdoor applications such as bridges, buildings, and architectural sculptures.
The ASTM A588 grade of Corten steel is another high-strength, low-alloy steel with improved atmospheric corrosion resistance. It has a yield strength of 50,000 psi (345 MPa) and a tensile strength of 70,000 psi (480 MPa). Its composition includes copper, nickel, chromium, and phosphorus. The A588 grade is commonly used for outdoor applications such as bridges, buildings, and architectural sculptures.
The price of Corten steel varies depending on the thickness of the material, the size of the sheet or plate, and the quantities ordered. As of September 2021, the average price for a 4x8 sheet of 16 gauge Corten steel is $406.48. However, prices can range from $300-$1,000 per sheet or plate depending on size and quantity.
Corten steel is a popular material for outdoor applications due to its unique appearance and durability. Its rustic orange-brown color and textured surface create an artistic and attractive look that can be used for both functional and decorative purposes. The weather-resistant properties of Corten steel make it ideal for outdoor structures such as bridges, retaining walls, and sculptures.
Overall, Corten steel is a high-quality and unique material that can add a special touch to any outdoor project. Its durability and resistance to atmospheric corrosion make it a popular choice for architects, designers, and builders looking for a reliable and long-lasting material for their outdoor structures.
