- Applications
- WF 300 is abasic non-alloying agglomerated flux for the submerged arc welding of stainless steels and high-alloyed Cr Ni Mo steels including duplex stainless steels.
- Characteristics
-
- - Excellent weldability such as stable arc and esay slag removal.
- - Excellent impact value at low temperature down to -196℃.
- - The weld metals show good mechanical properties.
- - Exceesive flux height may bring out poor bead appearance.
- - Redry the flux at 250~350℃ for 60 minutes before use.
- - Add new flux periodically when continuously reusing the flux.
