ABSTRACT OF THE DISCLOSURE This invention relates to an improved process for the manufacture of steels containing nickel, and more parti- cularly to the provision of such an improved process for the manufacture of corrosion-resistant steels. The specification discloses, in the process for the manufacture of steels con- taining nickel through the refining of a metal bath in a converter, the improvement which comprises adding ferro-nickel shot into the converter while controlling the flow rate of the shot in such a way that the temperature of the converter is maintained at a pre-selected level. The initial carbon and silicon levels of the metal bath may be higher than 1% and 0.4% respectively. The added ferro-nickel shot may comprise highly refined shot, the carbon content of which is, at most, equal to the carbon content of the metal bath after the refining process has been completed. The ferro-nickel shot may comprise slightly refined shot, the silicon content of which is, at least, equal to 0.4% by weight.
