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.

Alloy X is a nickel-chromium-molybdenum “superalloy” used for MIG, TIG or plasma arc welding of similar base metals such as Hastelloy X to itself or to stainless steel, carbon steel and low alloy steels. This filler metal offers an exceptional combination of oxidation, corrosion and thermal shock resistance. The weld deposits of Alloy X exhibit high temperature strength and resists weld metal fatigue at temperatures up to 2200°F. Alloy X is commonly used in the aerospace industry for engine tailpipes, turbine blades, nozzle vanes and after burner components. It is also used in petrochemical applications to combat stress corrosion cracking.
