Description:

Elgatig 183CR is a 1.25% Cr/0.5% Mo alloyed wire intended for TIG welding creep resisting steels of

similar composition, used in power generation plant operating at temperatures up to 570°C, e.g. DIN

13 CrMo 44, GS-17 CrMo 55, BS 3604 Grades 620 and 621 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 150-200°C is recommended. Post-weld heat treat at 690°C.
