ASTM A847 Corten Steel Round Pipe & Tubes

Corten Steel ASTM A423 Round Pipes & Tubes

The ASTM A847 specification covers cold-formed welded and seamless high-strength, low-alloy structural tubing. It is used for round, square, rectangular, or special-shaped tubes in welded, riveted, or bolted construction of bridges, buildings, and general structural applications requiring high strength and enhanced atmospheric corrosion resistance.

ASTM A847 Corten Weathering Steel Tube stands out for its superior tensile and yield strength, making it a top choice in the market. Produced with high-quality materials and advanced technology, it offers several outstanding features such as a skilled workforce, quality resources, and on-time delivery.

ASME SA847 Corten Steel Tube will naturally rust when exposed to weather conditions, with increased rusting if the material gets wet. To enhance its performance, a high-temperature underlayment is recommended during installation.

While ASTM A847 Corten Weathering Steel Piping is not rustproof, it welds and weathers at a similar rate to other materials, requiring appropriate welding techniques and drainage considerations to prevent corrosion in areas where water may accumulate.

ASTM A847 Tube is specifically designed for structures requiring welding and bolting, providing high strength and enhanced corrosion resistance. It is cold-formed, welded, and shaped into square and rectangular sizes, ensuring chemical consistency throughout the surface without adding outside metal during welding. The cold-forming process enhances its physical properties, offering a minimum yield strength of 50ksi and a minimum tensile strength of 70ksi.

Key Features and Benefits of ASTM A847 Steel:

  1. 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.
  2. 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.
  3. 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.
  4. 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.

Applications of ASTM A847 Steel Tubing:

  1. Structural Components: ASTM A847 steel tubing is widely used in structural components such as bridges, buildings, and transmission towers. Its high strength, corrosion resistance, and lightweight properties make it a preferred choice for these critical structural applications, ensuring long-lasting durability and structural integrity.
  2. Architectural and Construction Applications: The unique weathered appearance of ASTM A847 steel tubing adds a visually appealing element to architectural projects. It is commonly utilized for facades, roofing systems, cladding, and other design elements that require both durability and aesthetic appeal. The weathering process not only enhances its visual appeal but also provides additional protection against corrosion, making it suitable for exterior architectural features.
  3. Outdoor Furniture and Sculptures: The corrosion-resistant nature and weathered appearance of ASTM A847 steel tubing make it ideal for outdoor furniture, art installations, and sculptures. Its ability to withstand environmental conditions ensures the longevity and beauty of such pieces, making it a popular choice among designers and artists for creating outdoor structures and artworks that stand the test of time.
