* Feature
Nichrome 40 is characterized by high resistivity, good oxidation resistance and very good form stability. It has good ductility after use and excellent weldability.
* Application
Typical applications include night-storage heaters, convection heaters, heavy-duty rheostats and fan heaters. It is also used in heating cables and rope heaters in defrosting and de-icing elements, electric blankets and pads, car seats, baseboard heaters, floor heaters, resistors, etc. This Nickel-Chrome-Iron alloy has been widely used for furnace elements in the critical temperature range between 816℃ and 982℃ in atmospheres where preferential oxidation of chromium takes place - the “Green Rot” range. Nichrome 40 is also widely used as electric heating element material in domestic appliances and other electric heating equipment at operating temperatures up to 1100℃. It has good ductility after use, good corrosion resistance except in sulfur containing atmospheres and certain controlled atmospheres and excellent weldability.
