Finox 4820 AC is the electrode for joint welding and surfacing on heat-resistant chromium and chromium-nickel steels and cast steels of the same or similar alloy at working temperatures of up to 1,100 °C and rustless, corrosion-resistant molybdenum-free chromium (-nickel) steel and cast steel types. The ferritic-austenitic weld metal is scale-resistant at air and oxidising (combustion) gases up to 1,100 °C and shows good resistance against reducing, sulphur-containing (combustion) gases.
