EN 10088-1 Grade X1CrNiMoN25-22-2 solution annealed (+AT) introduction

Material X 2 CrNiMoN 25 22, (now: X1CrNiMoN25-22-2 ), material number 1.4466 is applicated acc. to VdTÜV-Wbl 415 : 2001-09 (sheets) for pressure vessels acc. to TRB 100 and AD-data sheet W 2 and W 10 from -195 to 400 °C (heavy duty). Further application in nuclear power engineering as far as nuclear regulations or object-related specifications permit use from -195 to 400 °C. Acc. to VdTÜV-Wbl 415-2 : 2002-03 (pipes, seamless) it is used for pressure vessels as per TU 100 and AD-data sheet W 2 from -10 to 400 °C. under full loading. Further application in nuclear power engineering as far as nuclear regulations or object-related specifications permit use from -10 to 400 °C. Acc. to VdTÜV-Wbl 415-3 : 2001-09 (section steel and bar steel, forged parts) it is applicable for pressure vessels as per TRB 100 and AD-data sheets W 2 and W 10 from -50 to 400 °C. Further application in nuclear power engineering as far as nuclear regulations or object-related specifications permit use from -50 to 400 °C. The welding suitability is examined allowing for generally accepted engineering rules for metal arc welding (VdTÜV-Wbl 415 : 2001-09 without subsequent heat treatment), MIG-welding with covered rod electrodes, metal arc welding with welding wire and welding rods (VdTÜV-Wbl 415-2 : 2002-03 preheating normally not necessary, intermediate temp. max. 200 °C., heat aftertreatment normally not necessary) and for arc hand welding resp. TIG-welding (VdTÜV-Wbl 415-3 : 2001-09 preheating normally not necessary, intermediate temp. max. 150 °C., heat aftertreatment normally not necessary). To the austenitic steel X1CrNiMoN25-22-2 nach DIN EN 10088-1 : 1995-04 applies: the material is comparable to X 2 CrNiMoN 25 22 2 acc. to Key to steel 1995 resp. Register of European steels 1994. It is a fully austenitic special steel with good corrosion resistance in the urea synthesis. It is resistant to intercrystalline corrosion also in sensitized condition and polishable.
