Characteristics and application
TIG/GTAW rod for 0.5%Mo steels. These steels are commonly used at service temperatures up to 500°C and for some sub-zero structural applications. The 0.5% alloying improves creep performance compared to CMn steels and sees the alloy being used for boiler, pressure vessel and piping construction. The good general mechanical properties also ensures use in general structural engineering applications.
Base materials
For similar alloyed high temperature steels and cast steels, ageing resistant and steels resistant to caustic cracking.
