TP317/317L, 1.4449, 1.4438

317 and 317L stainless steel pipe use molybdenum-bearing austenitic grades considered for suitable corrosive process environments. The low-carbon 317L grade may be preferred for welded fabrication, but final selection should follow the process medium, temperature, pressure, fabrication, and applicable standard.

For quotation, specify 317 or 317L, the product standard, manufacturing route, dimensions, length, heat treatment, testing, quantity, and documentation. Compare 316L, review all material grades, or send your technical requirements.
