Category:
Product Description
Standards：
GB/T17854 F309L-H00Cr24Ni13 F316L-H00Cr19Ni12Mo2
Introduction：
WD-SJ617 is the flux for electroslag overlay welding with electrode, fine powder particles, using flat characteristic DC power supply overlay welding. The electroslag process is stable, showing fast slag removal, beautiful weld channel formation, and good fusion at the lap between the weld channels, with no carbon increase, less Cr burning loss. It is suitable for electroslag overlay welding with a width of 30~75mm.
Applications：
It can be used for overlay welding of corrosion-resistant stainless steel for nuclear vessels, hydrogenation reactors and pressure vessels, etc.
