FLUX CORE WIRE : SOREX SFC-2209
Gas Shielded Stainless Steel Flux Cored Wire (SFC-2209)
Fabricating heavy-section duplex stainless steel equipment—such as offshore oil platforms, chemical tankers, desalination plants, and pulp processing digesters—demands welding consumables that combine high productivity with rigorous metallurgical protection. The Gas Shielded Stainless Steel Flux Cored Wire (SFC-2209) series from Thermatech delivers exceptional corrosion resistance and mechanical strength powered by Wire Sorex SFC-2209 manufacturing precision.
Classified under AWS A5.22 E2209T1-1 / E2209T1-4, Gas Shielded Stainless Steel Flux Cored Wire (SFC-2209) is alloyed with high Chromium (22%), Nickel (9%), Molybdenum (3.5%), and Nitrogen to ensure high Pitting Resistance Equivalent Numbers (PREN ≥ 34). Featuring a fast-freezing titania slag, this Wire Sorex SFC-2209 consumable supports stable spray-like arc transfer across flat, vertical-up, and overhead positions. Compatible with 100% CO2 or ArgonCO2 shielding gas blends, it yields smooth, spatter-free weld beads with self-peeling slag that consistently pass 100% radiographic non-destructive testing (NDT).
SFC-2209 is designed to weld duplex stainless steels such as UNS S31803 (Alloy 2205) with excellent pitting corrosion resistance, stress corrosion resistance and crack resistance. The weld metal can be applied for operation temperature up to 250%C and is resistant in chloride containing media against pitting corrosion as well as crevice and stress corrosion.
APPLICATIONS :
Typical applications include pumps, vessels, heat exchanger, chemical equipments and pipes processing chloride containing solutions.
NOTE ON USAGE:
1. Use DC (+) polarity.
2. Maintain a higher welding speed in order to get enough penetration in the down hand welding position.
Technical Advantages of Gas Shielded Stainless Steel Flux Cored Wire (SFC-2209)
Engineered for code-compliant fabrication and high-efficiency duplex welding operations, this product line offers distinct operational benefits:
- Superior Resistance to Pitting & Stress Corrosion Cracking: High Mo, Cr, and N alloying prevents pitting and crevice attack in aggressive chloride, saltwater, and acidic environments.
- Balanced Duplex Microstructure: Maintains optimum Ferrite-Austenite ratios (40–60%) in weld metal, preventing hot cracking during multi-pass welding and avoiding joint embrittlement.
- High Travel Speeds & Metal Deposition: Wire Sorex SFC-2209 flux-cored technology dramatically increases metal deposition rates over conventional GTAW (TIG) or solid MIG wires, lowering total labor costs.
- Self-Detaching Slag Layer: The slag layer peels away effortlessly upon cooling, leaving a clean, bright duplex bead profile with minimal post-weld grinding and joint preparation.

FAQ: Frequently Asked Questions About Gas Shielded Stainless Steel Flux Cored Wire (SFC-2209)
Q: Why choose Gas Shielded Stainless Steel Flux Cored Wire (SFC-2209) for duplex stainless steel welding?
A: Gas Shielded Stainless Steel Flux Cored Wire (SFC-2209) matches the chemistry of 2205 / UNS S31803 duplex steels. It provides high tensile strength, excellent impact toughness, and high PREN ratings to protect against chloride pitting and stress corrosion cracking in extreme marine or chemical environments.
Q: Which shielding gas provides optimal results with this Wire Sorex SFC-2209 product?
A: This Wire Sorex SFC-2209 consumable works excellently with 100% CO₂ gas for deep penetration and economical operation. However, utilizing an 80% Argon / 20% CO₂ blend provides lower spatter levels, superior arc transfer, and enhanced bead appearance.
