SINOPSIS

Experimental results of refining and nitriding of High Nitrogen Steels in an air-tight plasma furnace are presented. The one-stage Pressure Plasma Melting Process (PPMP) was realized under elevated pressure up to 0.5 MP a for a high Cr and Mn steel. Metallic calcium or CaF2-Ca alloy were used as the refining agent. The steel ingots cast under elevated pressure were hot forged to receive round bars and after their solutioning the samples were prepared to determine their mechanical properties.
