Detalles
ULTRACORE® 308L P delivers consistent mechanical properties, superior arc performance, and easy slag removal. Can be used when welding Nitrogen bearing 304LN and titanium stabilized 321.
Características
- Precision layer wound spool delivers steady spool payoff and more consistent feeding
- Smooth arc action with minimal spatter reduces post-weld cleaning
- Polished weld bead appearance reduces post-weld brushing
