Weldcote E309L-16 Stainless Steel Electrodes Are Used For Welding 22%Cr-12%Ni Stainless Steel, Mild Or Carbon Steel To Stainless Steel And Stainless Clad Steel. This Electrode Will Produce An Austenitic-Ferritic, Ductile Weld Deposit That Contains A Maximum Of 0.04% Carbon, Thereby Providing A Good Crack Resistance Superior To That Of 309 Electrodes. Typical Applications Are Similar To Those Of 309-16, But Where Stronger, Corrosion Resistance Is Required.
