Uranus50 (VdTÜV WB 456 : 1983-07) X 5 CrNiMoCu 21 7 VdTÜV WB 456 : 1983-07 Valid Germany 1.1.2 -30 - 250 1)
1) Remark: The ferritic-austenitic rolled and forged steel X 5 CrNiMoCu 21 7 (ferrite content 40 to 60 %) is used acc. VdTÜV-Wbl 456 : 1983-07 for pressure vessels acc. to TRB 100 as well as AD-data sheets W 2 and W 10 from -30 to 275 °C. For application in nuclear power engineering single or additional expertises necessary if it is defined in nuclear regulations or object-related specifications. This steel is resistant to intercrystalline corrosion. It shows an embrittlement tendency at 475 °C. and above the operating temperature. The notch impact energy may decline after 1000 h at 310 °C. to 50 % of the original values. A short overstepping of the operating temperature of 275 °C. to max. 300 °C. is allowed. The weldability is given for metal-arc welding and gas metal-arc welding (type similar and if necessary full austenitic (wire) rod electrodes). No preheating and no heat treatment are necessary. The working temperature should not exceed 180 degrees C.
