HBE-309MoL Stainless Steel Flux-cored Wire 
Standard:GB/T17853 E309MoLT-1 AWS A5.22 E309MoLT-1 JIS Z3223 TS309MoL-FB1
ØFeatures:HBE-309MoL consists of low C-22Cr-12Ni-Mo and suitable for all-positions welding. Stableelectric arc, less spatter, stable mechanical properties and better slog detachabilitywhen welding. Theaddition ofMo would refine the crack resistance.
Ø Applications:To be used on dissimilar steel welding of stainless steel with carbon steel or low alloy steel;back welding of Cr18-Ni12-Mo2 stainless steel clad plates. In the hard facing and repair surface process ofcarbon steel and low alloy steel, it also can be apply to backwelding of 316 or 316L stainless steel.
Ø Note:1.Ensure the purity of shielding gas and mixing ratio of properly mixed gas iswell controlled, withflow at 20-25L/min.
2.Keep the electrode extension between 15-25mm.
3.Recommended current (DCEP)Wire to be contacted with positive pole.
4. Please clean the appearance of base metal before welding.
5.Use the wire under the best possible condition. It should be used up as soon as possible if it'sunpacked.
