- Applications
- WT-317L is designed for the welding of low carbon 18% Cr-12%Ni-2%Mo and 19%Cr-13%Ni-3%Mo stainless steels.
- Characteristics on Usage
-
- - WT-317L is a rutile type flux cored wire for all-position welding.
- - It has self-detaching slag, spray-like arc transfer, excellent weldability and increased creep resistance at elevated temperature.
- - It contains higher levels of Mo for increased corrosion-resistance when compared to the WT-316L.
- - The weld metal contains optimum ferrite contents in their austenitic structures, Therefore their weldability is excellent with lower crack susceptibility.
- Notes on Usage
-
- - The shielding gas should be used 100% CO2 or Ar+20~25% CO2 for welding.
- - Gas flow rate is proper 20~25ℓ/min.
