Calcium-silicate type, agglomerated submerged arc welding flux, which is designed for butt and fillet welding stainless steel and corrosion resistance steels. It is also suitable to use in surfacing of stainless steels and unalloyed steels with stainless steel welding wire. Cr alloy content of the flux prevents Cr loss in stainless steel weld bead during welding. Provides good welding characteristics and easy slag removal even on thin section welding.
