DETAILS
THY-A316LQ (E316LT1-1) is a rutile-type C1 gas-shielded extra-low carbon stainless steel flux-cored wire. Delivering all-position capability, high molybdenum content, and excellent corrosion resistance, it is specifically designed for welding extra-low carbon 18%Cr-12%Ni-2%Mo stainless steel structures.
Features
- Rutile-type slag system optimized for 100% CO₂ (C1) gas shielding
- High molybdenum (Mo) addition provides exceptional resistance to pitting, crevice, and acid corrosion
- Extra-low carbon content minimizes carbide precipitation and enhances intergranular corrosion resistance
- Exceptional all-position welding capability with a stable arc, minimal spatter, and easy slag removal
Typical Applications
- Welding extra-low carbon 18%Cr-12%Ni-2%Mo stainless steels (e.g., AISI 316, 316L)
- Petrochemical, chemical processing, and fertilizer industry equipment
- Pressure vessels, boilers, and high-pressure storage tanks
- Food machinery, pharmaceutical processing, and medical apparatus fabrication
- Marine structures and coastal stainless steel engineering projects
Welding Positions
- PA / PB / PC / PD / PE / PF
WARNING
- Use DC⁺ only.
- Maintain wire extension at 20 mm and shielding gas flow rate at 20–25 L/min.
- Keep interpass temperature below 120°C (250°F).
