Description:
Cromarod 625 is a basic flux coated nickel-base electrode intended for welding Inconel 625 and
similar composition alloys which are primarily used for their excellent corrosion and oxidation
resistance. They exhibit an exceptionally high resistance to pitting corrosion and chloride induced
stress corrosion cracking. The electrode is very suitable for a wide range of dissimilar joint
combinations between nickel-base alloys, mild and low alloy steels and stainless steels, especially
where high temperature service conditions prevail. It can also be used to clad carbon steels with a
high strength, highly corrosion resistant surface. Cromarod 625 weld metal gives good fracture
toughness at temperatures down to -196 °C and is suitable for welding 5% and 9% nickel steels for
cryogenic applications.
