316LN Stainless Steel Pipe

Dec 19, 2025

Leave a message

316LN stainless steel is a low-carbon, nitrogen, strengthened version of 316. Higher yield strength than 316/316L. UNS S31653 material offers Mo and N, providing resistance to pitting and crevice corrosion. 316LN is ideal for chemical, marine, and acidic environments. Low carbon makes it less prone to intergranular corrosion after welding. We are a professional supplier of 1.4406 stainless steel materials, offering various sizes and Customized services.

SS 316LN Tube Factory Fabrication

 

Machining: Hot working temperature range is 1150°C - 1200°C, allowing for rapid forging and rolling at high temperatures. Excellent cold working performance, Easily formed by bending, stretching, deep drawing, and spinning.

 

1.4406 Material Solution Annealing

 

Heated at 1900-2150°F (1040-1175°C), then air-cooled or water-quenched.

 

Weldability: Suitable for various welding processes such as TIG and MIG welding. E/ER316L or E/ER316LN welding materials are acceptable. No post-weld heat treatment is required.

 

316LN VS 316L

 

316L (low carbon, C≤0.03%) has a typical yield strength ≥ 170 MPa. Lower price.

 

316LN (low C + N) has a typical yield strength ≥ 240 MPa, approximately 40% higher than 316L. Therefore, under the same pressure, 316LN can use thinner pipe walls, saving material costs.
