We offer ASTM A269 TP316L stainless steel tubing in welded and seamless processes, ASTM A269 TP316L is an austenitic stainless steel grade containing molybdenum content, and the higher nickel and low carbon content offer better overall corrosion-resistant properties than 304, especially about pitting and crevice corrosion in chloride environments, ASTM A269 TP316L stainless steel tubing is used for general corrosion-resisting and low-or high-temperature service.
ASTM A269 standard specifies 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, custom sizes are available upon requirements. ASTM A269 TP316L tubing can be finished in bright annealing (BA) and polished surface condition.
