Product Description
- All-position flux-cored wire developed to join low and medium carbon steel with 100% CO2 shielding gas.
- Displays exceptional impact properties — CVN impact values well exceed AWS A5.20 minimums at -20°C.
- Dual-classified E71T-1C and E71T-9C per AWS A5.20, providing maximum specification flexibility.
- High deposition rates and excellent penetration for increased productivity in structural and heavy fabrication applications.
- Typical applications include construction, shipbuilding, rail car, bridge fabrication, and heavy equipment industries.
- Diffusible hydrogen ≤ 8 mL/100g (H8 designation) for reduced risk of hydrogen-induced cracking.
- AWS A5.20 certified | ABS Approved
