EN 10088-1 Grade X2CrNiMo18-14-3 Solution Annealed (+AT): Superior Corrosion Resistance for Chemical & Pharmaceutical Applications

Material X2CrNiMo18-14-3 is comparable to X 2 CrNiMo 18 14 3 acc. to DIN17440 : 1985-07. This material is a variant of 1.4404 with slightly increased alloying contents of Cr, Ni and Mo, therefore improved corrosion properties. It is resistant to intercrystalline corrosion also in sensitized condition. Application in chemical apparatus engineering as well as in cellulose, textile and pharmaceutical industry.
