HASTELLOY® W RTW™ Filler Metal

Product Description:

HASTELLOY® W RTW™ filler metal is used for the gas metal arc and gas tungsten arc welding of dissimilar solid solution strengthened nickel alloys. The filler metal is widely used for that purpose in gas turbines, aerospace and chemical process industries. The RTW™ finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
