Abstract The expressions of the dependence of the solubility of nitrogen in the moltengray cast iron on the temperature and composition of melts were advanced under the conditionsof foundry practice. Three gray cast iron specimens with different compositions were examinedin good agreement with derived expression.

Key words: gray cast iron nitrogen solubility
