Abstract: A casting steel having high strength and low thermal expansion which has a chemical composition in mass %: C: 0.1 to 0.8 %, Si: 0.1 to 1.0 %, Mn: 0.1 to 1.0 %, S: 0.01 to 0.1 %, Ni: more than 40 % and not more than 50 %, Co: 4 % or less (including 0 %), Cr: more than 1.5 % and not more than 4 %, Al: 0.01 to 0.1 %, Mg: 0.001 to 0.1 % and balance: substantially Fe. The casting steel can be suitably used for a part having a ring shape which exhibits a low average thermal expansion coefficient in the temperature range of 20 to 500˚C, a high strength at 500˚C and good resistance to oxidation and thus can be used as a blade ring or a ring for retaining a seal ring for use in a gas turbine.

Abstract: The present invention provides a cast steel for ring-shaped components that has a low average coefficient of thermal expansion in a temperature range of 20°C to 500°C and high strength and good oxidation resistance at 500°C, which are required for ring-shaped components for use as blade rings and seal ring retainers of gas turbines, and that can hence be used for blade rings and seal ring retainers of gas turbines. Specifically, the present invention provides a high-strength and low-thermal expansion cast steel comprising, on a mass percentage basis, 0.1 to 0.8% of C, 0.1 to 1.0% of Si, 0.1 to 1.0% of Mn, 0.01 to 0.1% of S, greater than 40% and up to 50% of Ni, not greater than 4% (inclusive of 0%) of Co, greater than 1.5% and up to 4% of Cr, 0.01 to 0.1% of Al, and 0.001 to 0.1% of Mg, the remainder being substantially Fe.
