ASTM A423 Gr 3 Welded Tube

Dinesh Tube is one of the most prominent manufacturers and suppliers of Corten Steel B Welded Pipes. Our Alloy Gr 3 Welded Tubes are of two types Gr 3 ERW Tubes and  Gr 3 EFW Tubes. It provides you with the best design, quality, and safety features that help you in meeting the critical application demands of the customer. Corten  Gr 3 Steel Tubing became more popular over the years other producing mills began to develop their own atmospheric corrosion resistant weathering steels. Meanwhile, ASTM stepped in and created what is considered equivalent specifications to these Corten weather-resistant steels in most applications. The anti-corrosive properties of Corten Gr 3 weather-resistant steel Pipes are better than those of other structural steels in many applications. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words, Corten Gr 3 weather-resistant steel tubing is allowed to rust in order to form the protective coating. Corten Gr 3 weather-resistant steel tubes exhibit superior corrosion resistance over regular carbon steel as a result of the development of a protective oxide film on the surface of the metal which slows down further corrosion. 

All our Corten Steel Tubes conform to international standards and are manufactured according to ASTM, ASME, DIN, ANSI, EN, WERKSTOFFE, JIS, BS standards. Each piece of pipe is fully tested by professionals according to international standards. Also available at the best possible rates in the market.

The testing of the material is done by the industry experts in order to ensure the efficiency of the B Welded Pipes before finally delivering them to the customers. The tests performed are mechanical test, hardness test, PMI test, IGC test, pitting resistance test, flaring test, general corrosion test, micro test, and macro tests.
