The A269 TPXM-10 Austenitic Stainless Steel Seamless and Welded Tubing, as defined by the ASTM A269/A269M-2014 standard, is a premium material choice for various industrial applications. This tubing boasts a unique chemical composition, mechanical properties, and heat treatment status that make it suitable for demanding environments.

Chemical Composition:

The A269 TPXM-10 tubing is composed of elements that ensure its superior corrosion resistance and mechanical strength. The chemical composition includes a maximum carbon content of 0.08%, silicon up to 1%, manganese ranging from 8% to 10%, phosphorus limited to 0.045%, sulfur not exceeding 0.03%, chromium between 19% and 21.5%, nickel from 5.5% to 7.5%, and nitrogen up to 0.4%. This balanced composition ensures the tubing's durability and stability.

Mechanical Properties:

The mechanical properties of A269 TPXM-10 tubing are exceptional. With a hardness of HBW ≥1040 after heat treatment, the tubing exhibits high strength and toughness. Its ductility and formability allow for easy bending, cutting, and welding operations, making it a versatile material for various fabrication needs.

Heat Treatment Status:

The A269 TPXM-10 tubing undergoes rigorous heat treatment to enhance its properties. The heat treatment process eliminates internal stresses, improving corrosion resistance and extending the tubing's service life.

Size Range:

The A269 TPXM-10 tubing is available in a wide range of sizes to cater to different applications. Typically, the tubing has an inner diameter of 6.4 millimeters (6.4 mm) or more and a nominal wall thickness of 0.020 inches (0.51 mm) or more. However, it's worth noting that mechanical performance requirements may not apply to tubes with inner diameters less than 1/8 inch (3.2 mm) or wall thicknesses less than 0.015 inch (0.38 mm).

Impact Testing:

To ensure the reliability of welded joints in the A269 TPXM-10 tubing, impact testing is performed. This testing assesses the tubing's toughness and resistance to impact loads, ensuring that the welded joints can withstand the stresses encountered in service.

Primary Applications:

The A269 TPXM-10 tubing finds widespread application in various industries due to its superior corrosion resistance and mechanical properties. It is commonly used in the transportation of gas, water, oil, and other fluids in general service applications. Its smooth inner walls and excellent sealing capabilities ensure efficient fluid flow while minimizing the risk of leaks and contamination.
