OK Flux 10.81 SAW

Type Acid

OK Flux 10.81 is an acid agglomerated Si- and Mn-alloying flux for submerged arc welding, most suitable for applications where dilution of base metal is high e.g. in fillet welding and butt welding of thin and medium thick plates with a small number of passes. The excellent welding properties associated with the acid slag system of OK Flux 10.81 allow high travel speeds in butt welding i.e. spiral welding of thin walled pipes and fillet welding where good bead shape, excellent slag removal and very good surface finish are essential.

Density approx. 1,25 kg/dm3

Basicity index 0,6
