S Ni 6625 (NiCr22Mo9Nb)

ERNiCrMo-3

Description:

Cromatig 625 is primarily intended for welding Inconel 625 and similar composition nickel base alloys

which are used for their excellent corrosion and oxidation resistance combined with an exceptionally

high resistance to pitting corrosion and chloride induced stress corrosion cracking. 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. Can be used to clad

carbon steels with a high strength, highly corrosion resistant surface.

Applications:

Suitable for welding the nickel base alloys 625 and 825 but also 6 Mo steels (ASTM S31254) and 9%

Ni steels for cryogenic applications..

Overlay welding of carbon or low alloy steels and dissimilar joints.

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.

Scaling temperature:

The weld metal is resistant to oxidation in air up

to 1150°C. (Very high tensile strength and yield

strength up to approx. 850°C. Rp 0.2%=300 MPa,

Rm=400 MPa)
