Influence of carbon, Silicon, nickel, manganese and copper content on susceptibility to hard-spotting in nickel-manganese-copper cast iron was determined. Over a hundred alloys were analysed, containing: 1.6÷4.7% C, 1.3÷3.3% Si, 2.4÷10.5% Ni, 0.2÷8.2% Mn, 0.1÷5.2% Cu, 0.14÷0.17% P and 0.02÷0.04% S. Tendency to hard-spotting was determined on the ground of a test consisting in measuring the height of hard-spotting in a casting chilled from its face (ASTM A 367-55T). The measurement results permitted developing a regression equation describing direction and intensity of individual element influence on tendency of the examined cast iron to solidifying in a metastable system. This equation, together with the nickel equivalent equation, permits proper selection of chemical composition of austenitic cast iron with flake graphite.
