description PROBLEM TO BE SOLVED: To remarkably improve the tensile-compressive fatigue limit in the material while its thermal crack resistance equal to that of NCM cast iron which is highly rated in particular or above is secured by specifying the compsn. of elements and the degree of saturation in carbon calculated from the relation amount the elements. SOLUTION: The content of each element is decided to the following, i.e., by weight, 3.10 to 3.45% C, 1.10 to 1.50% Si, 0.60 to 1.00% Mn, 1.00 to 2.00% Ni, 0.30 to 0.60% Cr, 0.30 to 0.50% Mo,
