Material Summary
316LN is a nitrogen alloyed austenitic stainless steel with Mo addition. Its low carbon content avoids intergranular corrosion, even after welding. 316LN exhibits an austenitic microstructure, free of deleterious carbide precipitations. The grade contains residual ferrite after solution annealing (1050 - 1150°C /1922 - 2102°F) and water quenching. Higher Molybdenum content improves uniform and localized corrosion resistance. Nitrogen addition improves the structure stability and increases the yield strength compared to 316L. Main properties of 316LN are: high ductility, good weldability. Typical applications are food and beverage processing industry, chemical industry and chemical tankers. A ferrite free, non magnetic version of the grade has been developed for nuclear physics applications at 4°K
