摘要
A study was made of the original charge on the structure and crack resistance of cast alloy Kh32N6L melted in an electric arc furnace using a charge of 100% metallized pellets. Cyclic tests of the samples were carried out at 500 and 600 degree C to model the operating conditions. The favorable effect of using metallized pellets in melting the metal, consisting in an increase in the purity and in the homogeneity of the austenite with respect to harmful and nonferrous impurities, and also in an improvement in the service properties of the metal, was verified under industrial conditions.
