ASTM A847 Corten Weathering Steel

ASTM A847 is a high-strength low alloy weathering steel that encompasses cold-formed welded square and rectangular tubing and pipe. This steel exhibits significantly better atmospheric corrosion resistance in most environments compared to carbon steel, whether or not copper is added. The specification is designed for welded, bolted, or riveted construction of bridges and other structures where both high strength and enhanced corrosion resistance are imperative.

With a minimum yield strength of 50ksi and a minimum tensile strength of 70ksi, ASTM A847 undergoes a cold forming and welding process to ensure chemical consistency throughout the entire tube surface.

No external metal is introduced during welding, and the cold forming process enhances its physical properties, resulting in a robust material with notable strength.

The application of ASTM A847 is particularly suited for structural purposes where weight reduction and improved corrosion resistance are critical. It is specifically tailored for use in structures requiring welding and bolting, standing out as the sole choice when both high strength and advanced corrosion resistance are necessary.

Often referred to as “Weathering Steel,” ASTM A847 steel tubing earns its name due to its ability to develop a stable oxide layer on its surface. This layer acts as protection against atmospheric corrosion, making the material similar to ASTM A588 and ASTM A606 Type 4 steels in terms of corrosion resistance and weathering characteristics. The unique combination of strength and corrosion resistance makes ASTM A847 a preferred choice in applications where durability, structural integrity, and weathering resilience are key considerations.

Key Features and Benefits of ASTM A847

  1. Enhanced Atmospheric Corrosion Resistance: ASTM A847 steel tubing incorporates elements such as copper, chromium, nickel, and phosphorus, significantly improving its corrosion resistance when compared to standard carbon steel. This characteristic makes it particularly suitable for outdoor applications exposed to harsh environmental conditions, including bridges, buildings, and various structures.
  2. High Strength and Durability: ASTM A847 steel tubing boasts high tensile and yield strength, providing exceptional structural integrity and load-bearing capabilities. Engineered to withstand heavy loads and dynamic forces, it proves suitable for a wide range of structural applications where strength and durability are paramount.
  3. Cost-Effective and Low Maintenance: The inherent corrosion-resistant properties of ASTM A847 steel tubing eliminate the need for additional protective coatings. This not only reduces maintenance requirements but also lowers overall lifecycle costs, making it a cost-effective choice for the construction of long-lasting structures.
  4. Aesthetic Appeal: Similar to other weathering steels, ASTM A847 develops a distinctive weathered appearance over time. Its warm tones and textured surface contribute to an aesthetically pleasing element, making it an attractive choice for architectural and artistic applications. The unique visual characteristics enhance the overall look of structures and installations.
