Abstract:
A nodular graphite cast iron, a method for fabricating a vane for a rotary compressor using nodular graphite cast iron, and a vane for a rotary compressor using the same are provided. The nodular graphite cast iron includes 3.4 wt % to 3.9 wt % of carbon (C), 2.0 wt % to 3.0 wt % of silicon (Si), 0.3 wt % to 1.0 wt % of manganese (Mn), 0.1 wt % to 1.0 wt % of chromium (Cr), 0.04 wt % to 0.15 wt % of titanium (Ti), less than 0.08 w % of phosphorus (P), less than 0.025 wt % of sulphur (S), 0.03 wt % to 0.05 wt % of magnesium (Mg), 0.02 wt % to 0.04 wt % of rare earth resource, iron (Fe) and impurities as the remnants, and includes a bainite matrix structure, nodular graphite, and 15 vol % to 35 vol % of carbide.
