  • E309

    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.

  • E316

    Features and Applications
    • Low carbon alloyed core wire austenitic electrode with basic coating for use in all industries where analogous steels, including higher carbon grades and ferritic 13% Cr types are welded. High ductility of weld metal, therefore preferably used for welding of heavy sections.
    • Very good out-of-position weldability.
    • Good low-temperature ductility down to -196°C.
    • Resistance to intergranular corrosion up to 400°C.
    • No requirement of preheating or postweld heat treatement of weld metal
