Alloys of iron and carbon

Ferrous Alloys. Many ancient objects allegedly made of iron actually consist not of the pure metal but of alloys of iron and carbon known by the generic name ferrous alloys. These can be broadly classified into two classes steel and cast iron. Steel is the common name for iron-carbon alloys in which the relative amount of carbon ranges between 0.03% and 2%. If the relative amount of carbon in the alloy exceeds 2%, the alloy is known as cast iron (see Table 33) (Angus 1976 Wertime 1961). Steel is outstanding because of the mechanical properties that it acquires when subjected to heat treatment, which causes changes in its structure and physical properties (see Textbox... 

Steel is an alloy of iron and carbon, containing typically up to 2% carbon. The addition of other metals in alloys can give special properties such as superior strength, hardness, durability or corrosion resistance. 

Chinese metalworkers develop a method of casting iron, producing a high-strength alloy of iron and carbon. 

The iron metals family of products may be classified into (1) the pure irons, such as ingot iron and wrought iron, which have only traces of carbon (see Table I) and other elements, and are very ductile (2) cast irons, which are alloys of iron and carbon, with or without other elements, and normally containing from 2.4 to 4.5% carbon (3) steels, which are alloys Df iron and carbon, with or without other elements, in which the carbon content seldom exceeds 1.7% (4) alloy steels whose properties mainly are attributed to the presence of one or more elements other than carbon. There are other groups and numerous subgroups in the total iron metals family. 

In its simplest form, steel is an alloy of iron and carbon. In general, there are other alloying elements present. Steel wires can vary in composition enormously, from simple C-Mn steel to alloy steels containing more than ten alloy additions. Control of impurities (mostly nonmetallic inclusions), chemical segregation,... 

Though water solutions, or aqueous solutions as they are known to the chemist, are probably the most familiar solutions, there are many other kinds of solutions. There are solid solutions such as metal alloys, although not all alloys form truly homogenous blends. Bronze is an alloy of copper and tin, brass is an alloy of copper and zinc, and steel is an alloy of iron and carbon.

Alloys are metallic substances containing two or more elements which are miscible when molten and do not separate when solidified. They may be liquid or solid. This mixture of elements, usually but not necessarily metals, allows careful manipulation of strength, melting point, corrosion resistance, magnetic, thermal, electrical, and other properties steel, for example, is an alloy of iron and carbon often present with nickel, chromium, copper, aluminium, boron, tungsten, manganese, cobalt, silicon, and other elements. 

Steels are alloys of iron and carbon, classified as mild-, medium-, or high-carbon steels, according to the percentage of carbon they contain. Pipes made from various kinds of steel having different chemical compositions are useful for different applications. Mild steel pipes have a carbon content between 0.16% and 0.29%. These are hard materials with low ductility. Mild steel pipes are coated to resist corrosion. The most frequently used mild steels are A-106 and A-S3. 

The story of mankind is intimately hnked to the discovery and successful use of metals and their alloys. Amongst them iron and steel - we could define steel as a generally hard, strong, durable, malleable alloy of iron and carbon, usually containing between 0.2 and 1.5 percent carbon, often with other constituents such as manganese. Chromium, nickel, molybdenum, copper, tungsten. Cobalt, or silicon, depending on the desired alloy properties, and widely used as a stractural material , have shaped our material world. 

Ferrousmetals include both iron and steel. Non-ferrous metals include copper, aluminum, gold, and silver. We can form an alloy by combining two or more metals. Engineers develop alloys to produce a metal with the desired properties. For example, steel is an alloy of iron and carbon. The carbon makes the steel alloy stronger than pure iron. Brass is an alloy of copper and zinc. 

Plain-carbon steels are essentially alloys of iron and carbon together with varying amounts of other elements such as manganese, sulphur, silicon and phosphoms. These additional elements are found in the raw materials used in the steel-making process and are present as impurities. Both sulphur and phosphorus are extremely harmful and cause brittleness in the steel - they are therefore kept to a minimum. The effect of these is offset by the presence of manganese. The carbon content varies up to about 1.4%, and it is this carbon which makes the steel harder and tougher and able to respond to the various heat-treatment processes. 

There are many types of cast iron available, covering a wide range of mechanical and physical properties. All of them can be easily cast into a variety of simple or complex shapes. Like steel, cast iron is an alloy of iron and carbon, but with the carbon content increased to between 2% and 4%. 

Cast steel is also called tool steel or high-carbon steel. It is an alloy of iron and carbon which is melted in airtight crucibles and then poured into moulds to form ingots. These ingots are then rolled or pressed Into various shapes from which the finished products are made. Cast steel can be hardened and tempered and is therefore ideal for manufacturing tools. Hammer heads, pliers, wire cutters, chisels, files and many machine parts are also made from cast steel.

Plain-carbon steels are essentially alloys of iron and carbon together with varying amounts of other elements such as manganese, sulphur, silicon and phosphorus. These additional elements are found in the raw materials used in the steelmaking process and are present as impurities. 

Conceptually, the creation of steel, an alloy of iron and carbon, is readily understood since it involves either the removal of impurities and adjusting the carbon content in iron or the addition of the proper amount of carbon to very pure iron. In the long history of steelmaking before the modern era, these subtractive and additive techniques were discovered empirically, by trial and error. As chemists and physicists developed a deeper understanding of elemental metals and alloys, they were able to facilitate the production of traditional steels and create many new steel alloys, which stimulated the progress of the industry in the twentieth century. 

Carbon steels are basically alloys of iron and carbon, vtfith only small amounts of other elements present. For most of the steels discussed here, the carbon content ranges up to 1 %. However, there are some specialty steels in which carbon content may range up to 2 %. Carbon steels always contain some manganese, silicon, phosphorus, and sulfur minor amounts of other elements may also be present. The American Iron and Steel Institute (AISI) specifies that carbon steel may contain up to 1.65 % manganese, 0.6 % silicon, and 0.6 % copper [i]. 

An alloy of iron and carbon was treated with sulfuric acid, in which only iron reacts. 

Smelting of iron to extract it from its ore is believed to have started around 1300 BC in Palestine. Tools of iron appeared about this time and an iron furnace has been found. Steel is basically an alloy of iron and carbon with the carbon content up to approximately 2 wt%. 

Steel, because of its strength, formability, abundance, and low cost is the primary metal used for structural applications. As the term "plain carbon steel" implies, these are alloys of iron and carbon. These steels were the first developed, are the least expensive, and have the widest range of applications.
