ABSTRACT:
To provide graphitic cast steel given with improved machining and mechanical properties, a large number of fine graphite nodules can be crystallized in the cast steel, and the occurrence of chain-like formation of graphite crystals can be avoided by limiting the Bi content in the cast steel to the range between 0.005% and 0.0150%. The composition essentially consists of 0.45 to 1.5 wt % carbon (C), 1.0 to 5.5 wt % silicon (Si), 0.008 to 0.25 wt % rare earth elements (REM), optionally, 0.002 to 0.020 wt % calcium (Ca, 0.005 to 0.0150 wt % bismuth (Bi), 0.005 to 0.080 wt % aluminum (Al), and balance iron (Fe) and inevitable impurities. The cast steel can achieve favorable machining and mechanical property even in its as cast condition.
