ER80S-B2
Description:
Elgamatic 183B2 is a 1.25% Cr/0.5% Mo alloyed wire intended for MIG/MAG 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. The wire
analysis conforms to the AWS 80S-B2 classification.
