1.4429, X2CrNiMoN17-13-3, AISI 316LN - specification and application

Austenitic acid-resistant steel resistant to intergranular and crevice corrosion with increased content of Nitrogen and Molybdenum. From standard grades of group 316 it is distinguished by significantly better resistance to chlorides, sea water, acids, cracks and product fatigue during work. In addition, the improved chemical composition allows the material to be used at elevated temperatures in much more aggressive environments than standard 316 steel.

It is used in the production of pump parts, installations and pipelines, parts of radiators, special tanks, heat exchangers, agitators, surgical instruments, prostheses, machine components in the pharmaceutical, chemical, petrochemical, cryogenic, cellulose and food processing industries.
