ABSTRACT:
The invention relates generally to aluminum containing iron-base alloys useful as electrical resistance heating elements. The aluminum containing iron-base alloys have a disordered body centered cubic structure and improved room temperature ductility, electrical resistivity, cyclic fatigue resistance, high temperature oxidation resistance, low and high temperature strength, and/or resistance to high temperature sagging. The alloy has an entirely ferritic microstructure which is free of austenite and includes, in weight %, 4 to 9.5% Al, 0.2-2.0% Ti, 0.5-2% Mo, 0.1 to 0.8% Zr, 0.01-0.5% C, balance Fe.
