Introduction:

AWS A5.9 ER309LSi. The main ingredient is C-23Cr-13Ni, stainless steel MIG wire, can be used for all-position welding. it has excellent welding performance, smooth and beautiful bead and fewer spatters, by the addition of Si, the molten iron flow very well, due to the low carbon content, so have good performance of corrosion resistance.

Application:

Used for welding carbon steel and stainless steel dissimilar materials, petrochemical insudtry such as transition metal container wall cladding or applied to poor toughness martensite, ferritic stainless steel.
