Description
GeKa – 309L-17 ELOX Electrodes (4.0mm) 4.5kg
The GeKa 309L-17 ELOX Electrode is a rutile coated low carbon electrode designed for use in high strength unalloyed and heat treatable steels, ferritic Cr, and austenitic CrNi steels, as well as austenitic Mn steels. It is ideal for welding similar type austenitic stainless steels, dissimilar metals, and for creating buffer layers on mild and low alloyed steels prior to build up or overlaying.
Features & Benefits:
- Suitable for welding similar type austenitic stainless steels, dissimilar metals, and for creating buffer layers on mild and low alloyed steels.
- Offers good crack resistance, especially with hard to weld steels.
- The weld metal contains a high percentage of ferrite, ensuring durability and strength.
- Requires re-drying for a minimum of 2 hours at temperatures ranging between 120°C and 200°C.
Common Applications:
- Ideal for welding high-strength unalloyed and heat-treatable steels, ferritic Cr, and austenitic CrNi steels.
- Suitable for welding unalloyed tempered steels, tool steels, hard manganese steels, and other hard-to-weld steels.
- Used in applications where joining of corrosion-resistant stainless steel with mild or low alloy steels is required.
Typical Base Material Grades
- High-strength unalloyed and heat-treatable steels, ferritic Cr and austenitic CrNi steels, austenitic Mn steels
- Unalloyed tempered steels, tool steels, hard manganese steels, hard-to-weld steels
