StarBlaze PRIME 2209
AWS A5.4: E2209-16 | DIN EN ISO 3581-A: E 22 9 3 N LR 12 | Werkstoff Nr. 1.4462
Excellent Corrosion Resistance, Superior Weldability, Duplex Stainless Steel Welding
A rutile-basic coated 22-9-3-N type non-synthetic electrode specially designed for welding corrosion-resistant duplex stainless steels. StarBlaze PRIME 2209 offers excellent resistance to intergranular corrosion, pitting corrosion, and stress corrosion cracking. The low carbon weld deposit ensures superior weldability, a smooth spatter-free arc, excellent bead appearance, and a balanced austenitic-ferritic microstructure with ferrite content of approximately 40–45%. Vacuum-packed for optimum moisture protection and consistent welding performance.
