Haynes Hastelloy G-35 description: HASTELLOY G-35 RTW filler metal is used for the gas metal arc and gas tungsten arc welding of
G-35 alloy. The weld metal has outstanding corrosion resistance to "wet process" phosphoric acid, other oxidizing acids, alkalis, and chloride-bearing media. The RTW™ fi nish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
