Merit
Cr30Ni70 is a nickel-chromium heating conductor alloy for operating temperatures of up to 1250 °C and often contains additives of rare earths for a higher resistance to oxidation, especially with frequent switching operations or broad temperature variations. The resistance to atmospheric corrosion at 20 °C is high up to the upper operating temperature the resistance to air and other oxygen-containing gases as well as to nitrogen-containing low-oxygen gases is high as well, yet it is low to oxidizing as well as reducing gases containing sulphur. The resistance to carbonizing is high.
Applications
Industrial electric furnaces, enamelling furnaces, household appliances, night-current storage space-heaters.
