EN 10250-4 Grade X2CrNiN23-4 solution annealed (+AT)
EN 10250-4 Grade X2CrNiN23-4 solution annealed (+AT) introduction
Make X2CrNiN23-4 is comparable to X 2 CrNiN 23 4 acc. to SEW 400 :1991-02. The material is a stainless Duplex-steel of high strength and hardness and favorable resistance to general corrosion, pitting corrosion and especially to stress corrosion. Furthermore it shows resistance to intercrystalline corrosion also insensitized condition. Application for leight weight constructions of longer durability and higher reliability, for heat-exchanger and pipelines in chloride-containing media, hydraulic tubes, feeder water preheater, agitator shafts, steam heating systems.
