Abstract: Tensile and impact data are presented for cast stainless steels tested at temperatures between 20°and –1960°C. The steels investigated were based on the 18Cr-8Ni, 18Cr-8Ni-Nb, 18Cr-10Ni-3Mo and 18Cr-10Ni-3Mo-Nb types. The influence of variation, in carbon and nickel contents on the properties and microstructure of each type of steel was examined. Increasing the carbon content within the range 0.05–0.1% lowered the impact properties of all the steels except the Cr-Ni-Mo types, in which carbon was deleterious only if present in amounts greater than about 0.1%. Optimum nickel contents in relation to impact properties are indicated for the respective types of steel.
