Material Description

Material Number Material Name Standard Standard Status Country VDA 231-106 classification Application temperature [°C]
X2CrNiSi1820 (VdTÜV WB 535 : 2001-09) X 2 CrNiSi 18 20 VdTÜV WB 535 : 2001-09 Valid Germany 1.1.2 -50 - 300 1)
1) Remark: The high silicon alloyed austenitic steel X 2 CrNiSi 18 20 is acc. to VdTÜV-Wbl 535 : 2001-09 applicable for pressure vessels acc. to TRB 100 as well as AD-data sheets W 2 and W 10 from -50 to 300 °C., for steam boilers acc. to TRD 101 up to 300 °C. Further application in nuclear power engineering as far as nuclear rules or object-related specifications permit use from -50 to 300 °C. The material is resistant to intercrystalline corrosion both in delivery and welded condition without heat treatment up to 300 °C.
