WD-617 Agglomerated Flux For S.A. Welding
Standards: GB/T 17854-1999 F309L-H00Cr24Ni13 316L-H00Cr19Ni12Mo2
Introduction
WD-617 is flux for electroslag hard surfacing, the flux is powder granular.WD-617 can be welded with flat characteristic DC for hard surfacing, electroslag process is stable. It has an excellent slag detachability, bead appearance is beautiful, the fusion of bead joint is well. The flux doesn’t increase Carbon and the consumption of Cr is low.WD-617 is applicable of electroslag hard surfacing on the solder strip of 30-75mm.
Applications
Hard surfacing of corrosion resistance stainless steels for nuclear vessel, hydrogenation reactor and pressure vessel, etc.

Typical chemical composition of deposited metal (%)
Notice:
1. Flux should be redried at 300~350°C for 2 hours.
2. All dust, oil and rust should be removed.
