What is A312 TP316L?

316L pipe to A312/SA312 for general corrosive service. Strength guide: min tensile ~485 MPa (70 ksi), min yield ~170 MPa (25 ksi) typical for A312 TP316L — confirm PO.

Typical applications

  • Welded chemical / petrochemical piping
  • Heat-exchanger and condenser related stainless lines
  • Marine-adjacent and brackish water services within PREN limits
  • Pharma / biotech process piping

Selection guidance

Specify 316L for as-welded chloride service. Step up to 317L, 904L, 6Mo or duplex 2205 when pitting risk exceeds 316L.

316L vs 304L vs duplex — quick compare

ChooseWhenWatch-outs
316LChloride / chemical process austenitic with MoNot a substitute for duplex in high PREN duty
304LLower chloride load / cost-sensitive utilityWeaker pitting resistance than 316L
Duplex 2205Higher strength + chloride resistanceDifferent welding / heat-input controls
