摘要： Disclosed is an improved skid rail used in furnaces, particularly, the furnaces for heating steel pieces for hot processing. The skid rail uses, as the material of the skid members thereof, an oxide-dispersion reinforced type super alloy which comprises certain amounts of Cr, Fe, Al and Ti, and optionally a certain amount of Co, the balance being Ni, and contains fine particles of a high melting point metal oxide such a Y.sub.2 O.sub.3, ZrO.sub.2 and Al.sub.2 O.sub.3 dispersed in the austenitic matrix of the alloy.
