Product Overview – ASTM A213 TP316 Seamless Tubes
ASTM A213 TP316 is a chromium-nickel-molybdenum stainless steel grade known for superior resistance to pitting, crevice corrosion, and chloride environments.
The addition of molybdenum significantly enhances corrosion resistance compared to TP304, making TP316 seamless tubes suitable for aggressive chemical and marine conditions.
These seamless stainless steel tubes are manufactured using hot finished or cold drawn processes to ensure uniform grain structure, precise dimensions, and high-pressure strength.
TP316 seamless tubes are widely used in heat exchangers, boilers, condensers, chemical processing plants, pharmaceutical units, marine systems, and oil & gas projects.
