Standards & Materials: ASTM A312 TP316/TP316L
ASTM A312 Grade TP316 and TP316L refer to the stainless steel 316 and 316L respectively. The prefix “TP” denotes “type” of the stainless steel. TP316 or TP316L pipes may be furnished in seamless or longitudinally welded types with butt welding ends or threaded ends. TP316 is derived from the classic “18-8” (TP304) stainless steel by adding molybdenum for enhanced pitting resistance in chloride environments. TP316L is the low carbon version of TP316, in which low carbon content improves sensitization for better welded corrosion resistance.
ASTM A312 TP316 and TP316L are designated with UNS S31600 and UNS S31603, respectively. Although more expensive, pipes made of TP316/ TP316L have higher level corrosion resistance than that of TP304/ TP304L. They can be used for a diversified range of corrosive chemical process piping which involves inks, rayon, photographic chemicals, paper, textiles, bleaches, and rubber
