- Applications
- Main uses are for thin plate stainless steels and for the welding of automotive mufflers in 22%Cr-12%Ni stainless steels.
- Characteristics on Usage
-
- - WT-M309L is a metal type stainless steel flux cored wire for welding of 22%Cr-12%Ni steel, heat resistant cast steel and for the joining of chrome nickel clad steels to Cr-Mo steel or mild steel. This wire is designed for flat and horizontal fillet welding.
- - It is weld metal contains ferrite in austenitic structure, it gives excellent weldability, good corrosion and heat resistance.
- Notes on Usage
-
- - The shielding gas should be used Ar+2~5% O2 for welding.
- - Gas flow rate is proper 20~25ℓ /min.
