Or stainless steel is an alloy of iron containing additions of carbon ranging between (0.2% - 2.0%) of the alloy by weight of the alloy type, which is a basic element in the added
alloy steel. If the carbon content of iron in excess of 1% and 2 becomes fragile and called in those cast iron case. Alloy steel containing concentrations of other metals such as nickel, chromium, vanadium and silicon Almoulibdinyum, phosphorus, sulfur, other elements. [1] The carbon and other elements Ptksah steel, preventing iron layers in the crystal structure of a slide over each other (dislocation). Depending on the items added to the alloy steel, shape and presence in the steel (solute elements in metal or precipitation in the metal), the properties of alloys, such as hardness, flexibility and resistance to flatten in the alloy ingot steel resulting from such additions vary.
When the carbon content in the alloy increases from (2.1%), called on the name of the alloy cast iron, which is characterized by low melting point and usability of Zbk (en). [1]
Steel produced using different methods before the Renaissance a long period, but they were not effective ways. The use of steel became more common after the development of methods of production in the seventeenth century. After the invention of the Bessemer process in the mid-nineteenth century, the steel production process huge quantities of inexpensive become. After you have added some modifications to this method, other methods such as Basic oxygen steelmaking, which reduced the cost of production and improve the quality of the metal appeared.
Today, steel is one of the most commonly used material in the world, producing an estimated 1,300 million tons per year, which is the basic element in the construction, equipment, ships, cars, machinery, household furnishings and arms sector. Steel classifies various newly arranged according to several international classification such as Society of Automotive Engineers standards for steel
