FE1705 Iron Aluminide (Fe3Al)

Iron Aluminide Description

Iron aluminide is a class of iron-based alloys with the chemical formula Fe3Al that offer excellent high-temperature oxidation and sulfidation resistance. It is a low-cost alternative to stainless steel. They resist corrosion by the formation of an adherent surface film of Al2O3. Iron aluminide is also more ductile than stainless steel. These properties, among others, make it a better material for some applications, despite its slightly higher cost. 

Iron Aluminide Specifications

• Al= 15.9%, Cr= 2.20, Fe= bal., Zr= 0.0, B= 0.01, Nb= 0.0, % C= 0.0

Iron Aluminide Properties & Benefits

High yield and ultimate tensile strength, lower density than stainless steel, excellent oxidation resistance up to 1,200 deg.C, Excellent sulfidation resistance at high temperatures, Excellent resistance to highly oxidizing molten salts.
