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.

Corrosion resistance

Very good resistance to general and intergranular

corrosion. Maximum resistance (practically

immune) to pitting corrosion, crevice corrosion and

stress corrosion cracking in chloride bearing

environments.

High temperature properties:

Non-scaling in air up to 1150 °C. Very high tensile

strength and yield strength up to approx. 850 °C

(Rp 0.2% ~400 MPa.
