MasterWeld 309L Stainless Steel Arc Welding Rods
MasterWeld 309L is a general purpose stainless steel electrode of 23/12 type designed for joining dissimilar stainless steels, of the most common types, to one another.
Primarily designed for fabrication applications where tolerance to dilution is exploited in joining 410, 304, 321, 316 to mild and low alloy steels for brackets, stiffeners etc.
Also employed as a buffer layer on mild steels and used on clad plate applications extensively. Similar cast and wrought steels can also be welded if the service conditions are below 400°C.
Has found its main usage in welding Cromweld CR12 for transportation construction.
