The material NiCr8020 with the material number 2.4869 is applied in the form of strips, sheets, tubes and wires for furnace
construction components and heating conductors.
 
This is a unique nickel-chromium heating conductor alloy, engineered to function optimally at operating temperatures
reaching up to 1150 °C. Distinctively, it often incorporates additives of rare earth elements. These additives significantly
enhance its oxidation resistance, particularly in scenarios involving frequent on-off switching operations or substantial
 temperature fluctuations.
 
Exhibiting remarkable atmospheric corrosion resistance at 20 °C, this alloy maintains a high level of resistance to air
and various oxygen-rich gases throughout its operational temperature range. It also demonstrates excellent resistance
to nitrogen-based low-oxygen gases. However, it shows relatively low resistance when exposed to both oxidizing
and reducing gases that contain sulfur.
