Product Description
Hyundai SF-309L Flux Cored Welding Wire (1.2mm, 15kg Spool) is a premium gas-shielded flux-cored welding wire engineered for joining dissimilar metals and welding stainless steel components that demand superior corrosion resistance and high-temperature strength. Designed for professional fabricators, pipeline welders, and industrial workshops, this 309L-grade wire delivers stable arc performance, low spatter, and excellent bead appearance across a wide range of welding positions.
Key Features
- Grade: 309L Stainless Steel Flux Cored Wire — ideal for dissimilar metal joints (carbon steel to stainless steel) and cladding/overlay applications
- Diameter: 1.2mm — versatile for medium to heavy-gauge welding
- Spool Weight: 15kg — reduces downtime from frequent wire changes, ideal for high-volume production welding
- Low Carbon Content ("L" designation): Minimizes carbide precipitation and reduces risk of intergranular corrosion in the heat-affected zone
- Excellent Toughness: Delivers high ductility and crack-resistant weld deposits, even in multi-pass applications
- Smooth Arc Characteristics: Stable arc transfer with minimal spatter for cleaner welds and less post-weld cleanup
- Slag System: Self-releasing slag for easy removal and faster inter-pass cleaning
- All-Position Welding: Suitable for flat, horizontal, vertical, and overhead welding positions
Common Applications
- Welding stainless steel to carbon or low-alloy steel (dissimilar metal joints)
- Chemical processing and petrochemical equipment
- Food and beverage processing equipment
- Pulp and paper industry components
- Buffer/cladding layers before stainless steel overlay
- Heat exchangers, pressure vessels, and pipe fabrication
- Shipbuilding and heavy fabrication industries
