Abstract
The manufacturing method of high-manganese spheroidal graphite cast iron with exhibiting low magnetism, and excellent wear resistance, castability, and machinability, and having a composition which consists of, 2.5 to 4.0 wt. % of C content, 1.5 to 6.0 wt. % of Si content, 7.0 to 18.0 wt. % of Mn content, and 0.015 to 0.1 wt. % of Mg content, and when the Mn content falls within the range of 7.0 to 10.0 wt. %, consists of 10.0 wt. % or smaller of Ni content, or when the Mn content falls within the range of 10.0 to 18.0 wt. %, consists of Ni content being in the range satisfies the following formula: [Mn wt. %>Ni wt. %],
