1.4511 (VdTÜV WB 422 : 2001-06) X 8 CrNb 17 1.4511 VdTÜV WB 422 : 2001-06 Valid Germany 1.1.2 ≤ 200 1)
1) Remark: Valid for cold rolled strip Material X 8 CrNb 17 (X3CrNb17), mat. number 1.4511 weladable (TIG) Application range up to 200 °C: for design certificated pocket boilers and helical tubes for boilers of the Viessmann Werke KG, Allendorf, Smelting: electric arc oven, vacuum treated, AOD-process acc. to DIN EN 10088-1 : 1995-08 applies: - comparable to X 6 CrNb 17 nach DIN 17441 : 1985-07 (here higher C-content!) - ferritic steel with the same corrosion properties as 1.4510 - shows increased stress corrosion resistance in bases and low chloride containing water - largely resistant in water, steam, weak acids and bases as well as in oxidizing acids - resistant to intercrystalline corrosion both in delivery and welded condition. - a metallic clean surface is a basic requirement for good corrosion resistance - not polishable Application: for welded components in washing machines (alkaline tank) and in chemical apparatus engineering (weak acids), in dairy, food, brewery, dyeing and soap industry. In construction trade X3CrNb17 is used for decorative components to be welded in interior design, such as racks, frames, interior decoration elements
