DETAILS
THY-A308LQ (E308LT1-1) is a rutile-type C1 gas-shielded extra-low carbon stainless steel flux-cored wire. It features all-position welding capability, excellent welding usability, and low crack sensitivity for joining low-carbon 18%Cr-8%Ni stainless steel structures.
Features
- Rutile-type slag system optimized for 100% CO₂ (C1) gas shielding
- Extra-low carbon content minimizes carbide precipitation and enhances intergranular corrosion resistance
- Exceptional all-position welding capability with low crack susceptibility
- Smooth, stable arc performance with minimal spatter and quick-freezing, easy-to-remove slag
Typical Applications
- Welding low-carbon 18%Cr-8%Ni stainless steels (e.g., AISI 301, 302, 304, 304L, 308L)
- Petrochemical, chemical processing, and fertilizer industry equipment
- Pressure vessels, industrial boilers, and high-pressure storage tanks
- Food machinery, pharmaceutical equipment, and medical apparatus manufacturing
- General high-efficiency stainless steel structural fabrication requiring superior joint integrity
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).
