What is Corten Steel?
Corten Steel Specifications
Corten steel is a type of corrosion-resistant steel developed by United States Steel Corporation. It is designed for applications requiring strength and a long lifespan. When exposed to different weather conditions, it forms a protective rust layer, called a patina, which prevents further corrosion.
Corten steel manufacturers have created their own versions of this steel. ASTM has set equivalent specifications to ensure consistency and reliability across different products. Our equivalent ASTM specifications include ASTM A588, A242, S355J0W, and S355J2W. These standards ensure that the steel maintains the same level of strength and corrosion resistance as Corten steel.
ASTM A588 Specifications
ASTM A588 is a high-strength, low-alloy structural steel with enhanced atmospheric corrosion resistance. It is used for various structural components like angles, channels, beams, steel plates, and bars. Designed for welded bridges and structures, A588 steel offers weight savings and increased durability, contributing to a longer life cycle due to its corrosion-resistant properties.
A588 steel outperforms carbon steels like A36 and A572-50 in atmospheric corrosion resistance, even without copper. It is suitable for many unpainted applications when exposed to the elements. With a minimum yield strength of 50 ksi and a minimum tensile strength of 70 ksi, ASTM A588 provides excellent strength and resilience, making it ideal for projects requiring high strength and corrosion resistance.
ASTM A242 Specifications
ASTM A242 is a high-strength, low-alloy structural steel designed for enhanced atmospheric corrosion resistance. It is commonly used for steel plates up to one-half inch thick, providing excellent durability and resilience in tough environmental conditions.
A242 steel offers superior corrosion resistance compared to carbon steels like A36 and A572-50, even without copper. It is ideal for various unpainted applications when exposed to the atmosphere.With a minimum yield strength of 50 ksi and a minimum tensile strength of 70 ksi, ASTM A242 delivers strong performance and durability, making it a great choice for projects requiring high strength and corrosion resistance.
ASTM A606-4 Specifications
Enhanced with additional alloying elements, A606-4 offers better corrosion resistance than carbon steels, whether copper is added or not. It can be used bare and exposed to the atmosphere.With a minimum yield strength of 50 ksi and a tensile strength of 70 ksi, ASTM A606-4 is a reliable and versatile choice for projects needing high strength and excellent corrosion resistance.
ASTM A709-50W Specifications
With an atmospheric corrosion index of 6.00 or higher, ASTM A709-50W outperforms regular carbon steel, even without copper. It can be left unpainted, showcasing its natural, durable patina, making it perfect for applications where unpainted steel is desired.
ASTM A871-65 Specifications
ASTM A871-65 can be used in various applications. It is primarily used in transmission and lighting poles, offering an aesthetically pleasing alternative to traditional galvanized structures. This steel blends strength and beauty, adding an artistic touch to structural engineering while standing resilient in the open air.
ASTM A572-65 Specifications
This steel is known for its precision, reliability, and ability to withstand harsh environments, making it perfect for high-performance, durable projects. Choose ASTM A572-65 for strength and longevity.
ASTM A847 Specifications
This steel works well for welded, bolted, or riveted construction. It can be used bare, without paint, and still last a long time with minimal upkeep. With a yield strength of at least 50 ksi and a tensile strength of 70 ksi, ASTM A847 is perfect for tough environments and important construction projects.
