309/309L-17 is a high alloyed chromium-nickel covered electrode with rutile coating for welding of dissimilar joints between stainless steel and mild or low alloyed steels. It is also used to create buffer layers with a composition of 18%Cr/8%Ni before overlay alloys are deposited. The electrode has excellent arc stability, low spatter and fast burn off rate with minimal stub loss. It is also characterized by improved moisture resistance, self peeling slag, high resistance to porosity and easy post weld finishing. It provides smooth uniform beads and works in any standard weld position. Typical applications include welding of stainless steel to low alloyed steels, buffer layers on low alloy steels before overlays with 304 composition, welding of stainless steels of 23%Cr/12%Ni type, joining of ferritic/martensitic stainless steels of 12-18%Cr type.
