Literature
Literature
- Rutile-Basic stainless steel electrode
- Weldable on AC and DCEP polarity
- Excellent weldability in all position welding except vertical down
- High resistance to weld porosity
- Easy slag removal
- PRIMALLOY® JS-308L can produce lower carbon content weld metal with higher resistance to intergranular corrosion
