Description	Corrosion-resistant 13% Cr and 1% Ni cast steels are used to produce castings for the Kaplan, Pelton and Francis turbines. These cast steels also have a satisfactory cavitation resistance. The oxidation re-melting process, where oxygen is blown into the bath, was elaborated with the aim of reducing the gas content (hydrogen and nitrogen) in re-melted Cr13Ni1 steel scrap. This technology was tested on and described for twenty-five melts, with special regard to oxygen-blowing conditions, mechanical properties (verified by the impact test) of the cast steel, and suppressing the formation of gas holes in the castings. A basic electric-arc furnace was used in the oxidation re-melting process of steel scrap. The measuring of bath temperature and oxygen activity in the bath, and the parallel sampling for chemical analysis of the bath were realized in selected melt periods. The heat treatment of cast samples of re-melted corrosion-resistant steels was as follows: homogenisation annealing at 1150°C / (6¸20 h - Corrosion-resistant 13% Cr and 1% Ni cast steels are used to produce castings for the Kaplan, Pelton and Francis turbines.
