ABSTRACT:
A moderately high carbon alloy grey iron having a carbon content ranging from 3.4% to 3.6% by weight and a primary alloying addition of the combination of molybdenum and copper in amounts by weight ranging from 0.25% to 0.40% and from about 0.30% to 0.60%, respectively for achieving thermal fatigue resistance and good machinability without adversely affecting chill depth, and with a relatively low silicon content of about 1.80% to 2.10%. The alloyed grey iron having the characteristics of:
