304LN are nitrogen alloyed austenitic stainless steels. Nitrogen increases the yield strength of austenitic grades without impairing their ductility. The properties 304LN are: high strength and excellent ductility, good resistance to intergranular corrosion in the aswelded condition, excellent fabrication properties, low temperature toughness 304LN is austenitic in the solution annealed condition (1000°C - 1100°C/1832°F - 2012°F) and rapid cooling in air or water. They contain a small amount of ferrite. 304LN is more stable than standard 304L grades against martensitic transformations induced by deformation at low temperature. The use of 304LN will usually result in notable weight savings in most structural or pressure retaining applications.
