Bare, corrosion-resistant, chromium-nickel welding rod for welding the 24%Cr, 13%Ni alloyed types of steel.
The alloy is also used for welding buffer layers on C/Mn steels and for welding dissi- milar joints. When using the wire for buffer layers and dissimilar joints, it is necessary to control the dilution of the weld.
ES TIG 309L has good general corrosion resistance.
When used for joining dissimilar materials, the corrosion resistance is of secon- dary importance.
