EN 10028-7 Grade X2CrNiMoN17-13-5 Solution Annealed (+AT) – Superior Corrosion Resistance for High-Performance Applications

The austenitic steel X2CrNiMoN17-13-5 shows a high resistance to pitting and crevice corrosion (improved properties than 1.4436) as well as to stress corrosion, highest general resistance in many organic acids of high concentration and temperature, e.g. in unoxidizing and chloride-containing media (seawater, hypochloride base), also in inorganic and mixed acids. Resistance to intercrystalline corrosion is given even in sensitized condition. Usable in pressure vessel construction. Application: in the reactor industry, offshore technology, chemical industry Application temperature: -200 to 550 °C
