1 Classifications Characteristics and field of use Grain size Packaging Advice Main constituents in % Basicity (Boniszewski) EN ISO14174 SAFB165DC/SAFB165DCH5 UV 420 TT/ UV 420 TT-LHis an agglomerated flux of fluoride basic type for joining and surfacing applications with general purpose structural steels, fine grained structural steels and creep resistant steels. It is characterized by its neutral metallurgical behaviour. When used in combination with suitable wire electrodes the weld metal has high toughness properties at subzero temperatures. It is suited for single wire and tandem welding. EN ISO 14174: 3-20 ( mm); 3-25 ( mm) 25 kg plastic valve bag, 500/1000 kg Big-Bag It is advisable to redry the welding flux for about 2 h at C ( F) prior to use.
