Features and uses:

• SFC-71J is a gas-shielded flux welding wire for 490N/mm grade 2 high-tensile steel.
• It has good welding operability in all positions, less smoke and dust, soft and stable arc, less spatter, good weld bead formation and shape, deep penetration, good slag removal, excellent radiographic detection performance, and excellent -40°C impact performance.
• Suitable for welding of ship hulls, cryogenic vessels, pipelines, etc.
