Product Overview – ASTM A269 TP316 Welded Tubes
ASTM A269 TP316 welded stainless steel tubes are developed for applications that require enhanced corrosion resistance compared with standard stainless steel grades.
The addition of molybdenum in SS 316 improves resistance to pitting, crevice corrosion, and chloride attack, making it highly suitable for marine and chemical environments.
These welded tubes are manufactured using high-quality stainless steel strips that undergo precision forming, automatic welding, solution annealing, and surface finishing processes to ensure dimensional accuracy and metallurgical consistency.
Because of their corrosion resistance and durability, ASTM A269 TP316 welded tubes are widely used in chemical processing equipment, pharmaceutical plants, marine piping systems, food processing facilities, and industrial heat exchangers.
