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.
