Chapter 7. Metallic Alloys and Their Use

This chapter reviews the most important metallic alloys available commercially. Metals are divided into ferrous and nonferrous alloys. Ferrous alloys include the various kinds of steel and cast iron. Steels are generally available as annealed, rolled, and tempered. Plain carbon steels contain carbon and manganese as alloying elements and are the least expensive. By the addition of small amounts of other elements that provide additional precipitation strengthening, one produces high-strength low-alloy (HSLA) steels, tool steels, and stainless steels. Cast irons contain more carbon and silicon than steels. Gray cast iron is corrosion-resistant, absorbs noise, and is self lubricating; it is very brittle. ...
