Premium quality 4% Ni-Cr-Mo case carburising steel melted by the VAR method. The typical supply condition of this grade is normalised and softened to aid the machinability before further machining and heat treatment. The resulting product is capable of developing a hard case and strong core with excellent transversal properties.
