The composition of the invention is novel, the production process is reasonable and clear, through two times of quenching and tempering, and the quenching and tempering temperature is determined through experiments, and the treatment is carried out at this temperature, which can greatly improve the toughness and wear resistance of nickel hard white cast iron , so that the cast iron is not easy to produce cracks during use, which improves the service life. The hardness after heat treatment in the as-cast state reaches 53HRC, and greatly saves the processing time of heat treatment and improves production efficiency.
