On the basis of economic considerations, Fe-Al-C alloy could be a good candidate for replacing some of the conventional stainless steel. Wherein, Al is used to replace the expensive alloy element in conventional Fe-Cr-C system. The aim of the research is to investigate harden ability and corrosion resistance of Fe-9Al-0,6C in the NaCl and H₂SO₄ solution. Thirty five kilograms of Fe-Al-C were prepared from mild steel scrap, high purity aluminium, and Fe-C. The alloy was prepared in an induction furnace under an argon atmosphere. Jominy test and microstructure were examined. And, the corrosion rate, were carried out with three-electrode polarization in 0.5% NaCl and 0.05 M H₂SO₄. The corrosion type and the morphology of the oxide scale were examined by optical microscopy and scanning electron microscope (SEM). Corrosions products were examined with EDS/EDAX. The optical micrograph shows that as cast Fe-9Al-0,6C alloy has ferrite and pearlite microstructure. The result of Jominy test shows that these alloy non-harden able. The result of corrosion testing showed that the alloy more resistance in NaCl than in H₂SO₄ solution. Optical micrograph and SEM analysis indicated that corrosion form is general corrosion and there is no trend toward intergranular attack.
