1.4439 (DIN EN 10296-2 : 2006-02) X2CrNiMoN17-13-5 1.4439 DIN EN 10296-2 : 2006-02 With DIN EN 10312 : 2005-12 replacement for DIN 17455 : 1999-02 Valid Germany X2CrNiMoN17-13-5 1.1.2 -196 - 400 1)
1) Remark: Material X2CrNiMoN17-13-5 is applicated for pressure vessels from -196 to 400 °C. and for pressure gas tanks from -196 to 400 °C. Further application in nuclear power engineering. The material shows high pitting and crevice corrosion resistance (more favorable properties than 1.4436) as well as stress corrosion resistance, highest general resistance in many organic acids with high concentration and temperature, e.g. in nonoxidizing acids and chloride containing media (seawater, hypochloride base), also in inorganic and mixed acids as well as resistance to intercrystalline corrosion also in sensitized condition. Application in reactor industry, offshore technology, chemical industry. The welding method for the tube manufacturing is up to the producer.
