<p>A skid rail for use in a furnace operating at high temperature is prepared by using an oxide-dispersion strengthened type heat resistant alloy, which consists essentially of 10-40% Cr and the balance of Fe and contains 0.1-2% of fine particles of high melting point metal oxide such as Y2O3 dispersed in the ferrite matrix. The alloy optionally further contains up to 5% Al, or up to 5% Al and up to 5% Ti, and constitutes skid members (4A) of the rail. The skid rail exhibits excellent properties against hot deformation, oxidation resistance, abrasion resistance, sulfidation resistance and thermal shock resistance. <IMAGE></p> |
