TJC Steel Group is proud to introduce the A269 TPXM-11 Austenitic Stainless Steel Seamless/Welded Tubing, a high-performance material that meets the stringent requirements of various industrial applications. This tubing is manufactured in accordance with the ASTM A269 standard, ensuring its quality and reliability.

Chemical Composition

The A269 TPXM-11 tubing boasts a unique chemical composition that offers excellent corrosion resistance and mechanical properties. It primarily contains Chromium (Cr) in the range of 19 to 21.5%, Nickel (Ni) between 5.5 and 7.5%, and Nitrogen (N) up to 0.4%. The carbon (C) content is limited to a maximum of 0.04%, while Silicon (Si) and Manganese (Mn) are present in small quantities. The low sulfur (S) and phosphorus (P) content further enhance the material's corrosion resistance.

Mechanical Properties

The A269 TPXM-11 tubing exhibits exceptional mechanical properties, including high strength and ductility. It is capable of sustaining high pressures and vibrations, making it suitable for demanding applications. The tubing also possesses good formability and weldability, allowing for easy manipulation and installation.

Heat Treatment State

All A269 TPXM-11 tubing undergoes a rigorous heat treatment process to ensure optimal mechanical properties and corrosion resistance. This treatment involves heating the material to a specific temperature and then cooling it in a controlled manner. The resulting microstructure of the tubing is refined, resulting in improved strength and toughness.

Size Range

The A269 TPXM-11 tubing is available in a wide range of sizes to cater to various application needs. The outer diameter can range from 1/8 inch (3.18 mm) to 48 inch (1219.2 mm), while the wall thickness can vary from 0.035 inch (0.89 mm) to 2.5 inch (63.5 mm). The tubing is typically supplied in lengths of 20 foot (6.1 meter) or 21 foot (6.4 meter), but custom lengths can also be produced upon request.

Impact Testing

To ensure the reliability and durability of the A269 TPXM-11 tubing, impact testing is performed on a regular basis. This testing involves subjecting the material to sudden and intense impacts to assess its toughness and resistance to cracking. The results of these tests help us ensure that the tubing meets the highest standards of quality and performance.

Main Application Scenarios

The A269 TPXM-11 tubing finds widespread applications in various industries, including chemical processing, petrochemicals, pharmaceutical production, and food processing. Its excellent corrosion resistance and mechanical properties make it ideal for handling corrosive fluids and gases in high-pressure and high-temperature environments.
