* Feature
Nichrome 70 withstands temperatures up to 1250°C
* Application
Used for corrosion resistant electric heating elements in industrial furnaces with reducing atmospheres. Highly resistant to "green rot" – a preferential intergranular oxidation of the chromium that is commonly experienced with other alloys under certain environmental conditions. Highly resistant to oxidation in air. Not recommend for use in MgO sheathed heating elements, or applications using nitrogen or carburizing atmospheres.
