Steel Gems Card › Application Finder › Pipe Materials for High-Temperature Steam APPLICATION & MATERIAL GUIDE Pipe Materials for High-Temperature Steam Material selection depends on design temperature, pressure, creep requirements and the governing piping or boiler code. Carbon steel may suit moderate conditions; Cr-Mo alloy families are considered as temperature and design demands increase.
