Golden Bridge F9AZ-EF1-F1 (JQ-SJ121T) Welding Flux
SKU:SJ121T-0055
JQ-SJ121T
JQ-SJ121T is a fluorine-alkali type sintered flux, which has excellent welding performance with smooth arc, effortless slag removal ability and optimal bead appearance.
Working with proper welding wire (such as JQ-WEF1), the product is applicable for welding base metal with tensile strength of 620MPa, such as WB36 and HY80, and it is mainly used in the fields such as pressure vessels and thermal power.
