Spheroidal Graphite Cast Iron has many advantages in mechanical properties and manufacturing, for example, weight reduction due to smaller density than that of steel, good properties of vibration and noise, low cost in machining and heat treatment of blanks due to near-net-shape casting. It has been reported that spheroidal graphite cast iron (FCD700-800) can be applied as a medium hardness gear material. Recently, High Strength Spheroidal Graphite Cast Iron (H-FCD800), which has high strength and elongations, which contains about 2.4% Cu in its matrix, has been developed. It is expected to use H-FCD800 to gear materials. The authors have reported that the surface durability of H-FCD800 rollers is superior to that of FCD700 and/or SCM435 rollers by using a disk machine which simulates the rolling and sliding action of gears. In this paper, load-carrying capacity of H-FCD800 gears, which includes surface durability and bending fatigue strength, is investigated using a power-circulating type gear testing machine.
