It is an austenitic electrode composed of low carbon alloy core wire and basic coated. It is used in all industries where similar alloy steels are welded, including high carbon steels such as 13% chrome ferritic steels.
High ductility of the weld metal, therefore preferably used for welding heavy sections.
Very good out of position weldability.
Good low-temperature ductility down to -196°C.
Resistant to intergranular corrosion up to 350°C.
Weld metal does not require preheating or postweld heat treatement.

Typical Base Material Grades
Used for buffer layer unalloyed or low alloyed steels, also when joining non-molibdenum-alloyed stainless and carbon steels. Joints and mixed joints between austenitic steels.
Used for mixed joints between austenitic and heat resistant steels.
Features and Applications
GeKa ELOX R 309L electrodes are widely used in carbon-stainless steel joints. for example, joining mild or low alloy steels with AISI 304.
If a service temperature above 370 °C or heat treatment is applied after welding dissimilar steels, embrittlement or cracking may occur. This requires procedural control.
Ferrite content of weld metal is greater than 8 FN and reduces the possibility of intergranular carbide precipitation. This thereby increases the resistance to intergranular corrosion without the use of niobium.
