ABSTRACT:
An iron cast having iron as a major component, and including C, Si, Mn, Cr, Mo and Ni, where the cast iron provides excellent heat resistance and oxidation resistance at high temperatures. The cast iron beneficially contains between 2.5 to 3.0% of C; 2.0 to 3.0% of Si; 0.8 to 1.2% of Mn; 1.7 to 3.0% of Cr; 0.025 to 0.06% of Mg; 0.15 to 0.4% of Mo; and 17.0 to 20.0% of Ni; but less than 0.1% of P; and less than 0.02% of S. The cast iron is suitable for extremely severe conditions at high temperatures, and can be used for an exhaust manifold for engines where temperature of the manifold may reach 850° C.
