1.4401 (DIN 17456 : 1999-02)	1.4401	DIN 17456 : 1999-02	DIN 17456 : 1999-02 replaced by DIN EN 10297-2 : 2006-02	Replaced	Germany	X5CrNiMo17-12-2	The material X5CrNiMo17-12-2 is an austenitic CrNiMo-steel with increased resistance to non oxidizing acids and halogenated media but to intercrystalline corrosion only in delivery condition. It is suitable for mirror finishing and well cold formable. Application for acid resistant apparatus in chemical and pharmaceutical industry, in cellulose, rubber, color, fatty acid, textile and rayon industry, petrochemistry, for medical and photographic goods, in sewage plants, for higher chloride contents. X5CrNiMo17-12-2 is used in construction engineering for components of highest corrosion loading, e.g. smokestacks, sanitary engineering.
