ASTM A249 TP 304 Tube

New Eagle Industrial Corporation stands as a prominent manufacturer and exporter of ASTM A249 304 tubes. With advanced manufacturing procedures, we produce these tubes in both standard and custom sizes based on the diverse requirements of various industries.


ASTM A249 is an internationally recognized standard that determines the specifications for welded austenitic steel boilers, superheaters, heat exchangers, and condenser tubes. The significance of ASTM A249 in the manufacturing of our ASTM A249 304 Tube is paramount. Following the ASTM standard, we fabricate these tubes such that they bear the rigours of high-temperature, high-pressure applications. The manufacturing process involves the automatic welding of rolled steel without any filler metal addition. The tubes then undergo a subsequent cold working and annealing process and then heat-treated to enhance their mechanical properties and meet the chemical composition requirements. They are tested thoroughly for quality and reliability, and adherence to ASTM A249 signifies our unwavering commitment to offering products that meet or even exceed industry expectations and standards.


Our Sa-249 Welded Tubing provides excellent protection against numerous industrial environments and corrosive chemicals. Our Alloy 304 Tubes can be efficiently welded using all standard techniques. Our stainless steel tubes are a specialized austenitic composition comprising predominantly of chromium and nickel, the non-iron constituents conferring its remarkable rust-resistance abilities.


Our SA 249 Tp 304 Material in industries extends to its corrosion resistance against most oxidizing acids, making it an ideal choice for kitchen and food applications. Owing to their higher chromium and lower carbon content, our SS Tubes demonstrate superior heat and corrosion-resistant attributes.


We infuse unique properties in our tubes to facilitate their applications in numerous fields, such as tanks and containers for solids and liquids, and process machinery in an array of industries, including chemical, cryogenic, mining, food, and pharmaceutical sectors. Fabricated with austenitic stainless steel that houses a high percentage of chromium and nickel, our tubes are used in highly corrosive conditions.


Rigorous destructive and non-destructive testing procedures on the finished tubes ensure their peak performance. Leveraging advanced tools, we maintain a substantial inventory to meet emergency or urgent delivery requirements. Products are packed using appropriate materials and delivered promptly to our customers at New Eagle Industrial Corporation.
