What is ASTM A269?
This specification covers nominal-wall-thickness， seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service. All material shall be furnished in the heat-treated condition. The steel shall conform to the chemical composition requirements.
Different mechanical test requirements that includes， flaring test， flange test， hardness test， and reverse flattening test are presented. Also， each tube shall be subjected to the non-destructive electric test or the hydrostatic test. Finally the hardness requirements for different grades of tubes are highlighted.
The tubing sizes and thicknesses usually furnished to this specification are 1/4 in. [6.4 mm] in inside diameter and larger and 0.020 in. [0.51 mm] in nominal wall-thickness and heavier.
Our range of Austenitic Stainless Steel 316 / 316L seamless tubes is in conformation with the international quality standards and is thoroughly tested on various parameters before delivering to the clients. Designed according to the national and international standards， this Stainless Steel Tubing is offered in made-to-order length sizes and shapes to our well-regarded customers.
