Do you need to validate the compliance of stainless steel tubing according to ASTM A269?
Securing fluid transfer circuits with ASTM A269
In the Aerospace, Space, and Defense (ASD) sectors, the reliability of hydraulic and fuel lines is a safety imperative. Even the slightest non-conformity in the steel grade can lead to corrosion phenomena or premature failure of your essential parts.
ASTM A269 defines the requirements for seamless and welded austenitic stainless steel tubing for general service. It imposes strict criteria on chemical composition, mechanical properties, and corrosion resistance tests to guarantee the integrity of tubular structures.
At FILAB, we support manufacturers in the ASD supply chain with the control and qualification of their tubing according to ASTM A269. Our goal is clear: to ensure the reliability of your technical and industrial decisions.
ASTM A269: a performance challenge for fluid networks
Compliance control of austenitic steels according to ASTM A269
ASTM A269 covers numerous steel grades (such as 304/304L or 316/316L). FILAB intervenes to verify that the supplied material respects the chemical limits and required physical aptitudes.
It is specifically used to:
- Verify chemical composition by spectrometry (ICP or Spark) to validate the steel grade.
- Analyze carbon content (ASTM E1019) to guarantee resistance to intergranular corrosion in "L" grades.
- Perform metallographic examinations (grain size, inclusion cleanliness).
In the Aerospace and Defense industries, compliance with ASTM A269 has a direct impact on:
- Corrosion resistance in aggressive environments.
- Weldability and formability of tubing during system integration.
- In-service behavior of strategic components subjected to vibrations and high internal pressures.

Our FAQ
ASTM A269 is intended for general service tubing (corrosion, low/high temperature), while ASTM A213 is more specific to boilers, superheaters, and heat exchangers, often with stricter mechanical requirements.
For grades like 316L, a carbon content that is too high (above 0.030%) can lead to sensitization of the steel during welding, causing premature corrosion. FILAB uses high-temperature combustion to guarantee this measurement.
Yes, our acid digestion techniques for ICP-OES allow us to work on samples of very low mass, which is ideal for precision tubing used in aerospace instrumentation.
