Abstract
A novel oxide-dispersion strengthened type heat-resistant alloy is provided for use of preparing furnace members such as a skid rail. The alloy consists essentially of up to about 0.2% C+N, up to about 2.0% Si, up to about 2.0% Mn, about 15 to 35% Ni and about 0.2 to 4% Ta, and the balance of Fe, and contains about 0.1-2% of fine particles of high melting point metal oxide such as Y.sub.2 O.sub.3 dispersed in the austenite matrix. The alloy exhibits excellent properties of anti-hot deformation, oxidation resistance, abrasion resistance and thermal shock resistance.
