Description:

Elgamatic 184CR is a copper coated wire for use with the MIG/MAG process, which deposits a 2.4%

Cr/1.0% Mo weld metal. It is intended for welding creep resisting steels of similar composition, used

in steam generation plant operating at temperatures up to 600°C, e.g. DIN 10 CrMo 9 10, GS-18

CrMo 9 10, GS-17 CrMo V 5 11, BS 3604 Grades 622 etc. Also suitable for use in the chemical and

petrochemical industries where resistance to hydrogen attack, corrosion from sulphur bearing crude

oil, and stress corrosion cracking in sour environments is required. Preheat and interpass

temperature of 200-250°C is recommended. Post-weld heat treat at 700°C.

Welding current:

DC+

Shielding gas:

C1, 100% CO2, 7-12 l/min

M21, 80% Ar + 20% CO2, 7-12 l/min
