EN 10222-5 X2CrNiMo18-14-3 Solution‑Annealed Grade for Corrosion‑Resistant Applications
Trademark X2CrNiMo18-14-3 is comparable to X 2 CrNiMo 18 14 3 acc. to DIN 17440-85. This material is a variant of 1.4404 with slightly increased alloying contents for Cr, Ni and Mo, thus 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.
