TP316N Stainless steel welded pipe for heat exchanger

ASME SA-249 (welded austenitic steel pipes for boilers, superheaters and heat exchangers), ASTM A312 (seamless and welded austenitic stainless steel pipes), meet the requirements of pressure vessels and high temperature environments.
TP316N Stainless steel welded pipe for heat exchanger is based on 316L, with nitrogen (N content 0.10-0.16%) added to strengthen it to form an austenitic structure, with both high strength and corrosion resistance.

ASME SA-249 TP316N welded pipe Features
Corrosion resistance: Cl⁻ pitting resistance is better than 316L, suitable for highly corrosive environments such as seawater and chemical solutions. Outstanding oxidation resistance and creep resistance at high temperatures ( Less than or equal to 450 degree ).
Mechanical properties: Tensile strength Greater than or equal to 629 MPa, elongation Greater than or equal to 73%, both high strength and high plasticity. No heat treatment is required after welding to maintain stable performance.
