Abstract: A method of making a heat treated steel casting comprising the steps of taking an "as-cast" steel casting comprising not more than 0.2% carbon, a total alloy content of less than about 4%, a carbon equivalent, as herein defined, lying in the range 0.45-0.7 and cooling the casting after performing the casting operation and then performing a heat treatment operation by re-heating the casting to a temperature above the AC.sub.3 temperature to homogenize the casting, then cooling the casting to an inter-critical temperature lying between the AC.sub.3 and AC.sub.1 temperature and then quenching to room temperature.

Abstract: A method of making an engineering ferrous metal comprising the steps of adding to liquid engineering ferrous metal solid alloy carbide particles and thereafter permitting the ferrous metal to solidify. The alloy carbide particles are coated with iron or an iron alloy to allow wetting to occur between the powder and the liquid ferrous metal and the particles have a density which matches that of the ferrous metal to provide a uniform distribution of the carbide particles in the ferrous metal. A roll may be made having at least a shell made of metal by such a method by centrifugal casting or electroslag remelting.
