Corten Steel ASTM A847 Pipe and Tube Supplier
ASTM A847 tubing is a type of weathering steel that encompasses high-strength low-alloy steel, covering cold-formed welded square and rectangular tubing and pipe. Its superior atmospheric corrosion resistance compared to carbon steel, with or without copper addition, makes it highly desirable for various applications.
Primarily intended for welded, bolted, or riveted construction of bridges and structures requiring high strength and enhanced corrosion resistance.
ASTM A847 tubing boasts a 50ksi minimum yield strength and a 70ksi minimum tensile strength.
The cold forming and welding processes ensure chemical consistency throughout the entire tube surface, without adding any outside metal. This enhances physical properties with a 50ksi minimum yield strength and a 70ksi minimum tensile strength. Designed specifically for structural applications prioritizing weight reduction and improved corrosion resistance, ASTM A847 weathering steel is the go-to choice where welding and bolting are necessary. Its ability to develop a stable oxide layer on the surface, akin to ASTM A588 and ASTM A606 Type 4 steels, earns it the moniker “Weathering Steel” due to its enhanced protection against atmospheric corrosion and robust weathering characteristics.
Key Features and Benefits of ASTM A847 Steel
- Enhanced Atmospheric Corrosion Resistance: ASTM A847 steel tubing is formulated with copper, chromium, nickel, and phosphorus, enhancing its corrosion resistance compared to standard carbon steel. This makes it ideal for outdoor applications exposed to harsh environmental conditions, such as bridges, buildings, and other structures.
- High Strength and Durability: ASTM A847 weathering steel tubing boasts high tensile and yield strength, providing excellent structural integrity and load-bearing capabilities. It is designed to withstand heavy loads and dynamic forces, making it suitable for a wide range of structural applications where strength and durability are paramount.
- Cost-Effective and Low Maintenance: The corrosion-resistant properties of ASTM A847 steel tubing eliminate the need for additional protective coatings, reducing maintenance requirements and overall lifecycle costs. This makes it a cost-effective choice for long-lasting structures that require minimal upkeep.
- Aesthetic Appeal: Similar to other weathering steels, ASTM A847 develops a distinctive weathered appearance over time. Its warm tones and textured surface add an aesthetically pleasing element to architectural and artistic applications, enhancing the visual appeal of structures and installations.
Corten Steel Tube specializes in producing square, rectangle, round, and specially shaped electric resistance welded (ERW) high-strength, low alloy (HSLA) atmospheric corrosion-resistant structural steel tubing to meet ASTM specification A847. This type of tubing, commonly known as weathering steel, utilizes elements like copper, chromium, nickel, and silicon to enhance protection and resistance against atmospheric corrosion.
ASTM A606 Type 4 high-strength, low-alloy (HSLA) steel, which is similar to ASTM A847, forms the basis for these tubes. The unique composition of these steels allows for the development of a weathered orange-brown oxide on the surface over time, providing a protective layer that inhibits corrosion. This natural weathering process makes ASTM A847 tubing suitable for use in unpainted conditions, particularly in outdoor applications where exposure to the elements is inevitable.
Additionally, the added strength of the steel itself allows for a lighter wall thickness compared to carbon steel tubing, while still meeting the structural physical requirements. This combination of enhanced corrosion resistance, reduced weight, and structural strength makes A847 tubing a practical and reliable choice for various structural and outdoor applications.
