Overview
Hastelloy X filler metal is used for the gas metal arc and gas tungsten arc welding of X alloy. The deposited weld metal has an exceptional combination of oxidation resistance, fabricability and high-temperature strength. It has also been found to be exceptionally resistant to stress-corrosion cracking in petrochemical applications. X alloy exhibits good ductility after prolonged exposure at temperatures of 1200, 1400, 1600°F (650, 760 and 870°℃) for 16,000 hours. The filler metal is also a good candidate for dissimilar welding between solid solution nickel based alloys and Ni-Fe-Cr alloys. The RTWM finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
