Solid copper coated wire for TIG, alloyed with 9%CR-1%Mo for creep-resisting steels.
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.
