Finox 4842 B
Finox 4842 B is a rod electrode for joint welding and surfacing on heat-resistant chromium-nickel steel and cast steel of the same or similar alloy at working temperatures of up to 1200 °C, for tough joints, intermediate and filler layers when welding chromium steel and cast steel. Further, this electrode is suitable for joining unalloyed and low-alloyed steel and cast steel or rustless and heat-resistant chromium steel and cast steel with austenitic steel and cast steel at working temperatures of up to 300 °C. The weld metal does not have sufficient resistance against reducing, sulphur-containing and carburising gases. A cover layer with Finox 4820 AC should be applied in these cases.
