1.4335 (DIN EN 10028-7 : 2000-06) X1CrNi25-21 1.4335 DIN EN 10028-7 : 2000-06 DIN EN 10028-7 : 2000-06 replaced by DIN EN 10028-7 : 2008-02 Replaced Germany X1CrNi25-21 1.1.2 1)
1) Remark: The material X1CrNi25-21 is comparable to X 1 CrNi 25 21 acc. to SEW 400-91. The steel is melted of restricted chemical analysis, it shows high corrosion resistance to oxidizing acids (especially nitrous acid). The material is resistant to intercrystalline corrosion also in sensitized condition. Application in urea synthesis, for construction parts with nitrous acid impact (max 70 % concentration) and increased temperature, in fertilizer industry as well as for various chemical processes.
