GEE GETIG ER90S-B3 TIG Welding Filler Wire

GETIG ER90S-B3 TIG Welding Filler Wire GEE GETIG 90SB3 / ER90SB3 is a copper-coated, 2.4% Chromium / 1.0% Molybdenum alloyed solid wire designed for TIG welding creep-resistant steels of similar composition. It is suitable for steam-generation plants operating at temperatures up to 600°C. The filler wire is also suitable for chemical and petrochemical industry applications where resistance to hydrogen attack, corrosion from sulphur-bearing crude oil, and stress corrosion cracking in sour environments is required.
