Flux Core Wire : Sorex SFC-81Ni1 (High strength low alloys FCW)
Fabricating low-alloy structural steel, offshore jacket legs, pressure equipment, and low-temperature storage tanks requires filler metal that delivers both high deposition efficiency and exceptional sub-zero notch toughness. The Gas-Shielded Flux Cored Wire for Low Alloy Steel (SFC-81Ni1) series from Thermatech delivers industrial-grade mechanical properties powered by Flux Core Wire Sorex engineering.
Featuring 1% Nickel alloying (AWS A5.29 E81T1-Ni1C / E81T1-Ni1M), Gas-Shielded Flux Cored Wire for Low Alloy Steel (SFC-81Ni1) produces weld deposits that maintain high impact resistance even at severe temperatures down to –40°C. Its fast-freezing titania slag system supports high-current vertical-up and overhead welding without weld puddle sagging or undercut. Compatible with 100% CO2 or Argon CO2 shielding gas blends, this Flux Core Wire Sorex consumable ensures low hydrogen levels, minimal spatter loss, and smooth, aesthetic bead contours that pass stringent non-destructive radiographic testing (NDT).
Technical Advantages of Gas-Shielded Flux Cored Wire for Low Alloy Steel (SFC-81Ni1)
Designed for heavy-duty structural steelwork and low-temperature engineering applications, this product line offers distinct advantages:
- Sub-Zero Impact Toughness: 1% Nickel addition guarantees high Charpy V-notch (CVN) energy absorption at $-40^\circ\text{C}$, preventing brittle fracture in cold environments.
- All-Position Usability: Smooth arc characteristics and fast-freezing slag enable high-speed positional welding with uniform bead profiles and minimal post-weld cleaning.
- X-Ray Quality & Low Hydrogen: Flux Core Wire Sorex moisture-resistant manufacturing guards against hydrogen entrapment, porosity, and cold cracking in thick low-alloy plates.
- High Deposition Efficiency: Gas-shielded flux-cored technology dramatically increases metal deposition rates over conventional stick (SMAW) electrodes, maximizing shop productivity.
DESCRIPTION :
SFC-81Ni1 is an all position flux cored wire designed for 100%CO2 shielding gas.
It can provide excellent weldability involved good bead appearance, less spatter,
stable arc and easy slag removal, but also qualified impact value down to -30°C.
APPLICATIONS :
It is suitable for welding of 550N/mm2 high tensile strength steel on bridge structure
storage tanks and construction machinery.
NOTE ON USAGE :
1. Use 100%CO2.
2. Proper heat input can obtain required impact value

FAQ: Frequently Asked Questions About Gas-Shielded Flux Cored Wire for Low Alloy Steel (SFC-81Ni1)
Q: Why choose Gas-Shielded Flux Cored Wire for Low Alloy Steel (SFC-81Ni1) for low-temperature applications?
A: Gas-Shielded Flux Cored Wire for Low Alloy Steel (SFC-81Ni1) is alloyed with 1% Nickel, which refines the ferrite grain structure of the weld deposit. This provides exceptional impact toughness and crack resistance down to -40°C, making it superior to standard carbon steel flux-cored wires for low-temperature service.
Q: What shielding gas should be used with this Flux Core Wire Sorex product?
A: This Flux Core Wire Sorex consumable can be used with either 100% CO₂ gas or an 80% Argon / 20% CO₂ mixture. Using the Argon/CO₂ blend provides lower spatter levels, smoother arc transfer, and slightly higher tensile strength.
