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.
