HAI-NiCr 70 or NiCr 70/30 Nickel-Chromium alloy for use at temperatures up to 1250°C
Common trade names NiCr 70/30, Resistohm 70, Nikrothal 70, Chromel 70/30, HAI-NiCr 70, Cronix 70, Inalloy 70, X30H70.
NiCr 70 30 (Werkstoff Nr 2.4658) is an austenitic Nickel-Chromium alloy for use at temperatures up to 1250°C. The 70/30 alloy is characterized by high resistivity and good oxidation resistance. It has good ductility after use and excellent weldability.
Uses: 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.
