Advantages of Stainless Steel 316LN Valves

These flexible Valve fittings offer numerous benefits for various industrial applications.

Enhanced Strength: Nitrogen addition enhances the tensile and the yield strength of the 316LN over the normal 316 stainless steel and hence it is suitable for pressure vessels.
Superior Corrosion Resistance: Offers very good resistance to general corrosion and localized corrosion in the form of pitting and crevice corrosion particularly in chloride containing environments. It is applied in marine and chemical processing sectors.
Improved Weldability: Can be easily welded since there is permission to use standard methods of welding such as TIG and MIG welding. Low carbon content of the alloy is desirable to ensure that corrosion resistance is achieved in the welded areas of the material.
Non-Magnetic: Other properties including the non-magnetic ones are retained in the annealed state that is useful in non-magnetic applications.
High Toughness: At the same time, the following mechanical properties are to be retained: high tensile strength and dimensional stability, good impact strength at the ambient temperature and at the service temperature.
Oxidation Resistance: Exhibits good oxidation resistance at high temperature, thus making the valves to have long life span especially in high temperature services.
