309LSi Stainless Steel MIG Welding Wire
MasterWeld 309L Stainless Steel MIG wire is a corrosion-resistant, chromium-nickel wire for welding the 24%Cr, 13%Ni-alloyed types of steel.
The alloy is also used for welding buffer layers on CMn steels and welding dissimilar joints.
When using the wire for buffer layers and dissimilar joints, it is necessary to control the dilution of the weld.
MasterWeld 309L offers good overall corrosion resistance. When used for joining dissimilar materials, the corrosion resistance is of secondary importance.
