Corten Steel ASTM A847 Pipe Supplier

ASTM A847 Corten Weathering Steel

Corten Steel Tube is a leading corten steel ASTM A847 welded pipe supplier & exporter in India. ASTM A847 is a high-strength low alloy weathering steel known for its cold-formed welded square and rectangular tubing and pipe. This steel offers superior atmospheric corrosion resistance compared to carbon steel, even without the addition of copper. It’s specifically designed for welded, bolted, or riveted construction in bridges and structures requiring both strength and corrosion resistance.

With a minimum yield strength of 50 ksi and a minimum tensile strength of 70 ksi, ASTM A847 welded pipe undergoes cold forming and welding processes to maintain chemical consistency throughout the tube surface. 

The application of ASTM A847 is ideal for structural purposes where weight reduction and enhanced corrosion resistance are crucial. It’s tailored for welding and bolting applications, making it the preferred choice when both high strength and advanced corrosion resistance are needed.

Referred to as “Weathering Steel,” ASTM A847 tubing develops a stable oxide layer (patina) on its surface upon exposure to atmospheric oxygen. This layer acts as a protective coating against further oxidation, similar to ASTM A588 and ASTM A606 Type 4 steels, enhancing its corrosion resistance and weathering characteristics.

Corten steels are distinguished by the oxide layer, known as the patina, that forms on their surface upon exposure to atmospheric oxygen. This patina is a thin protective coating that acts as a barrier against further oxidation. The ASTM A847 HSS Welded Square Pipe is part of the ASTM A847 specification, which covers a range of Corten steel products. There are also other specifications tailored for specific applications such as pressure vessels, high-temperature environments, acidic, and chemical applications, among others.

ASTM A847 HSS Welded Square Pipe is part of this specification, which also includes variants for pressure vessels, high-temperature, acidic, and chemical applications. The different grades of Corten steels find use in diverse applications like Corten Steel Exhaust Pipes, known for their high strength and low alloys suitable for welding and bolting.

The specifications for A847 Corten Steel Welded Pipes and Tubes range from 1 inch to 6 inches in nominal diameter, with wall thickness varying from 0.133 inches to 0.280 inches. 

As a leading Grade 1 Corten Steel Pipe supplier, we ensure top-quality products suitable for high corrosion resistance and structural strength applications.
