TIG ER80S-B2

Description:

ER80S-B2 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.   The Mn content fulfils the AWS classification B2.  Preheat and interpass temperature of 150-200°c is recommended.  Post-weld heat treat at 690°c.
