BGS-2594
TIG Welding Wire for Stainless Steel
Austenitic-ferritic duplex type
Compliance:
YB/T 5092 H022Cr25Ni9Mo4N
AWS A5.9 ER2594
AWS A5.9M ER2594
EN ISO 14343-A: W 25 9 4 N L
EN ISO 14343-B:SS2594
Often used in the marine industry, primarily for welding super duplex stainless steels such as UNS S32750, UNS J93380, and also often used for root welding of standard duplex steel pipes such as UNS S32205 and J92205.
1. Main chemical composition: 25.5%Cr-9.2%Ni-3.5%Mo-0.25N;
2. Because the weld metal contains ferrite phase with PREN ≥ 40, it has good resistance to pitting corrosion, crevice corrosion and stress corrosion cracking;
3. Stable arc, good seam formation, excellent welding properties.
