Results show that RE and heat, treatment improves the morphology and the distribution of carbide and increases the impact toughness of high C-Cr cast steel.

The high carbon cast steel shot is the most widely used metal abrasive for blast cleaning and shot peening at present,and applicable for blast cleaning and shot peening of the metallic surface in the fields about autoindustry,shipbuilding,rolling stock,aerocraft,bridge,container,mechanical manufacturing,steel structure,pressure reservoir,stone etc.

The ERVIN life of the high carbon cast steel shot after double-quenching and tempering was measured using 100% replacement method.

Practice for Process of EAF Carbon Pick-up Operation for Production of Medium and High Carbon Steels;

The medium and high carbon steels were quenched with and without magnetic field in the self-made quench tank,the austenite transformation in the NaCl solution was studied,and the microstructure change after phase transformation was observed.
