Carbon Steels
More than 90 percent of all steels are carbon steels. Machines, automobile bodies, most structural steel for buildings, ship hulls, bedsprings, and bobby pins are among the products made of carbon steels.
Alloy Steels
These steels have a specified composition, containing certain percentages of vanadium, molybdenum, or other elements, as well as larger amounts of manganese, silicon, and copper than do the regular carbon steels. Automobile gears and axles, roller skates, and carving knives are some of the many things that are made of alloy steels.
High-Strength Low-Alloy Steels
They cost less than the regular alloy steels because they contain only small amounts of the expensive alloying elements. Girders can be made thinner without sacrificing their strength, and additional space is left for offices and apartments.
Stainless Steels
Stainless steels contain chromium, nickel, and other alloying elements that keep them bright and rust resistant in spite of moisture or the action of corrosive acids and gases. In kitchens and in plants where food is prepared, handling equipment is often made of stainless steel because it does not taint the food and can be easily cleaned.
Tool Steels
They contain tungsten, molybdenum, and other alloying elements that give them extra strength, hardness, and resistance to wear. These steels are fabricated into many types of tools or into the cutting and shaping parts of power-driven machinery for various manufacturing operations.
