Maxflux SAF-8 (LS) CTOD is a fluoride-basic agglomerated type flux suitable to weld medium to high strength steels and good CTOD fracture toughness properties was achieved for offshore constructions. The weld metal made with this flux gives very low diffusible hydrogen content, good crack resistance and higher sub-zero toughness properties. The flux is neutral in Mn & Si pick up and meets mechanical requirements after post-weld heat treatment at 620 C up to six hours of holding. The weld deposit is of radiographic quality. The weld metal passes the corrosion tests as per NACE standard TM-01-77 & TM-02-84.
Maxflux SAF-8 (LS) CTOD is suitable for single & multi-layer welding of high tensile
quenched & tempered steel, fine grained steels, heat resistant structural steels,
nuclear sector fabrication, etc.
Re-dry the flux at 300-350 C for two hours before use.
