2016-5-16  The ductile iron connecting rod experienced an average life of 1,605,902 cycles at a 50% survival rate or 635,811 cycles at a 90% survival rate. Presumably, one of the reasons for the improved life in the ductile iron rods is because the nodular form of the graphite in ductile iron is more spherical than in malleable iron. In malleable iron, the
