Product Description:
HASTELLOY® 622 RTW™ filler metal is used for weld overlay applications and has an enriched chemistry for outstanding resistance to pitting, crevice corrosion and stress-corrosion cracking. It has excellent resistance to oxidizing aqueous media including wet chlorine. The weld metal has excellent resistance to preferential corrosive attack in various media and thus is a great candidate for overlay and cladding of carbon steels. The alloy makes a great candidate for dissimilar welding of other nickel-chromium-molybdenum alloys and stainless steels. The RTW™ finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
