ASTM A213 TP317L Seamless Tubes:

ASTM A213 TP317L Seamless Tube covered under specification ASTM A213 is designed to be a part of systems involving the use of either steel boiler, superheater, or heat-exchanger tubes. The L after grade 317 indicates that the SA 213 TP 317L is a lower carbon containing alloy.

Lowering the content of carbon in the production of grade SS 317L Welded Tubing is what ensures that the alloy does not become prone to intergranular corrosion, which in turn stems from the UNS S31700 Round Tubing being used at elevated temperatures especially in the chromium carbide precipitation range. Hence, the A213 TP317L Seamless Tube can be used in an as welded condition.

As opposed to grade 316L, the ASTM A213 TP317L Seamless Tube proves to be a valuable asset in strongly corrosive environments which contain compounds like sulfurous media, chlorides, and other halides with its resistance to corrosion.
