Summary: | The present invention addresses the problem of providing a free-cutting stainless-steel cast product which can satisfy all of excellent cuttability, environmental preservation, and corrosion resistance and a process for producing the cast product. The stainless-steel cast product contains an agent for imparting free-cutting properties, and has a configuration characterized in that the agent for imparting free-cutting properties is h-BN particles and has been evenly and dispersedly precipitated in the steel. The process has a configuration characterized in that a stainless-steel cast product containing h-BN particles precipitated therein is heated and then quenched to cause the h-BN particles to disappear through formation of a solid solution and the cast product is thereafter tempered to thereby dispersedly reprecipitate h-BN particles. |
