1.2mm X 15kg – SFC-71M A5.18 E70C-6M
Product Certification
Features and uses:
- SFC-71M is a flux-coated welding wire based on metal powder for 490N/mm grade 2 high-tensile steel.
- It has good workability, less smoke and spatter, good weld bead formation and shape, deep penetration, excellent radiographic detection performance, and excellent impact performance.
- Suitable for welding of ship hulls, storage tanks, engineering machinery, bridge structures, steel structures, and pipelines.
Notes:
- Use CO2 as the protective gas with a flow rate of 15~25 l/min. To obtain better workability, 75~80% Ar + 20~25% CO2 can be used as the protective gas.
