Abstract The possibility of the development of Fe-Mn-Al austenitic steels has been investigated with special attention paid to the effect of Mo, W, Ti, V, Cr or Si on the stability of austenite, their high-temperature strength and tonghness, as well as their resistance to oxidation and corrosion.It was found that two alloys have good tensile and stress-rupture properties comparable to those of high Cr-Ni bearing steels such as 257 Ti and one alloy has oxidation resisting property similar to that of 13% Cr steel. However, their corrosion resistance is rather poor and this seems to be the main objection for them to be used as high-temperature steels. Cladding and surface coating are suggested as possible remedies.Some of the alloys have low magnetic permeability and high impact values at-178℃, thus enabling them to be considered as potential non-magnetic and low-temperature steels.
