SC-91K2 Cored

SC-91K2 Cored is a rutile type flux cored arc welding wire to be used with CO2 shielding gas. Deposited weld metal toughness is good at low temperature range down –40℃. To achieve good weld metal qualities, heat input must be controlled, not to exceed general welding condition. Welding arc is stable and bead appearance is good in all position welding. Diffusible hydrogen content is low and crack resistance is excellent
