We have a new shipment of ASTM A312 TP316/TP316L Seamless stainless steel pipe for our Vietnam customer
ASTM A312 Grade TP316 and TP316L refer to stainless steel 316 and 316L, respectively. The prefix “TP” indicates the “type” of stainless steel. TP316 or TP316L pipe is available in seamless or longitudinally welded types, with butt-welded or threaded ends. TP316 is derived from the classic “18-8” (TP304) stainless steel with the addition of molybdenum for enhanced pitting resistance in chloride environments. TP316L is a low carbon version of TP316 where the low carbon content increases sensitization for better weld corrosion resistance.
