Casting is one of the basic processes used for the shaping of steel. It is economical in both cost and time of production. Numerous components are produced from cast steel because of the advantages of the process. These advantages can best be described under the following headings: design flexibility, metallurgical versatility and quality, and economic benefits. This chapter looks at these advantages of steel castings. Of major interest is the comparison of cast steel with wrought steel and weldments in terms of properties, availability, cost, and quality. The chapter also includes information on cast steel compared to other cast metals and other methods of steel fabrication.

This chapter describes important requirements for ferrous and nonferrous alloys used for gears. Wrought surface-hardening and through-hardening carbon and alloy steels are the most widely used of all gear materials and are emphasized in this chapter. The processing characteristics of gear steels and the bending fatigue strength and properties of carburized steels are reviewed. In addition to wrought steels, the chapter provides information on the other iron-base alloys that are used for gears, namely cast carbon and alloy steels, gray and ductile cast irons, powder metallurgy irons and steels, stainless steels, and tool steels. In terms of nonferrous alloys, the chapter addresses copper-base alloys, die cast aluminum alloys, zinc alloys, and magnesium alloys.
