HASTELLOY® G-30® RTW™ Filler Metal
HASTELLOY® G-30® RTW™ Filler Metal is used for the gas metal arc, gas tungsten arc, and submerged arc welding of G-30® alloy. G-30® alloy is also used for welding 6-7 molybdenum-bearing stainless steels and duplex grades including 2507. The alloy has many applications in phosphoric and nitric acid productions, as well as, pul and paper fabrications. G-30® alloy is considered an overmatching filler metal for the 6-7 molybdenum bearing stainless grades and also the duplex grades including 2507. Hastelloy® G-3 was replaced by G-30.
