FCW 825
Basic flux cored stainless steel wire, with high-alloy strip for gas shielded metal arc welding
Description & applications
• Basic flux cored stainless steel wire, with high-alloy strip for gas shielded metal arc welding
• Fully austenitic Cr-Ni-Mo-Cu weld metal
• Exclusive slag system and fine tuning of the compositional balance increase resistance against cracking
• Deposit is resistant against stress corrosion cracking, crevice corrosion, pitting corrosion and intergranular corrosion
• Maximum performances in the horizontal and downhand positions
• Welded with classical economical Ar-CO2 mixtures
APPLICATIONS
• Cladding alloy 825
• Welding stainless steels of similar composition or joining leaner austenitic stainless steels
