What is A213 TP316L?

316L seamless tube for heat-transfer service. Chemistry: 16–18% Cr, 10–14% Ni, 2–3% Mo, C ≤ 0.030%. min tensile ~485 MPa (70 ksi), min yield ~170 MPa (25 ksi) typical for A312 TP316L — confirm PO.

Typical applications

• Boiler, superheater and heat-exchanger tubes
• Welded chemical / petrochemical piping
• Heat-exchanger and condenser related stainless lines
• Marine-adjacent and brackish water services within PREN limits

Selection guidance

Specify 316L for as-welded chloride service. Step up to 317L, 904L, 6Mo or duplex 2205 when pitting risk exceeds 316L. Confirm OD × average/min wall, length and U-bend needs on the enquiry.
