Rod for gas welding of 0.5%Mo steels, i.e. P1. 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. Viscous melting bath. Extremly useful when the exact analysis of the boiler plate is unknown.
