316LN stainless is a nitrogen-strengthened version of Type 316L stainless. By means of solid solution strengthening, the nitrogen provides significantly higher yield and tensile strength as annealed than Type 316L without adversely affecting ductility, corrosion resistance or non-magnetic properties. In the hot rolled unannealed condition, yield strengths of 75 ksi (518 MPa)or higher can be achieved for bar diameters up to 1.375in (34.925 mm).

316LN stainless has good resistance to atmospheric corrosion and long-term resistance to general corrosion when embedded in concrete. In the 15 week corrosion macrocell test in simulated concrete pore solution, 316LN stainless had an average corrosion rate less than 0.25 micro-meter/yr.

In general, the corrosion resistance of 316LN stainless is similar to Type 316L. The higher nitrogen content enhances chloride pitting and crevice corrosion resistance.

316LN withstands not only ordinary rusting but also most of the organic and inorganic chemicals. It resists corrosion by nitric acid and sulfurous acid compounds.

316LN has good intergranular corrosion in the as-annealed and as-welded conditions due to its low carbon content. Some intergranular attack may occur in the hot rolled unannealed condition.

For optimum corrosion resistance, surfaces must be free of scale, lubricants, foreign particles, and coatings applied for drawing and heading. After fabrication of parts, cleaning and/or passivation should be consi
