Summary:PURPOSE:To improve the strength and toughness by adding prescribed percentages of C, Si, Mn, Ni, Cr, Mo, etc. and reducing the amount of S to <=0.01% to prevent segregation. CONSTITUTION:The titled cast steel contains, by weight, 0.01-0.06% C, <=1% Si, 0.5-4% Mn, 1-4.5% Ni, 10-14% Cr, 0.2-1% Mo, 0.01-0.05% one or more among Mg, Ca and Ce, and <=0.01% S. The steel has superior strength and toughness, and it is suitable for use as the material of members of a hydraulic machine used in water flowing at high speed such as the runner and propeller of a water turbine.
