GeKa Elhard 600S - Hard facing MMA rods 3.2mm 5kg - 3010101809
Perfect for drag and contact welding as well as positional welding. These rods can be applied as a final hard facing layer on machine parts such as digger buckets or drilling and crushing teeth. Even perfect for edging on cutting blades and other hardened steels. Generally if it is a metal that needs to have high wear resistance then this is for you.
Rods include chromium-silicon alloy resulting in a very hard electrode. Finishing after weld should be achieved by grinding. It is recommended to pre-heat your work to a temperature between 200 and 300ºC. For best results in wear resistance it is recommended to run 2 or 3 layers of hard facing rod.
If you need to rebake these rods they require a minimum time of 2 hours at 300ºC.
