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.
- Re-drying: 120-200ºC / 2 h.
