Basic metal powder type. Creep-resisting 9CrMo electrode made on high purity low carbon core wire. Moisture-resistant coating gives very low weld metal hydrogen levels. Recovery is about 120% with respect to the core wire, and 65% with respect to the whole electrode.
Applications
For elevated temperature service up to 600ºC, with a reasonable degree of corrosion resistance in superheated steam, hot hydrogen gas and high sulphur crude oils, where higher performance than 5%Cr-0.5%Mo steels is required. Used primarily for boiler superheater tubing, heat exchangers, piping and pressure vessels in oil refineries and power plants.
