To get started you need to burn excess carbon because after getting blast furnace iron in which carbon from 2.14 to 6.67%.The steel contains 0.2 to 2.14% carbon.It reached a level of carbon in the open-hearth furnace or a converter, where the chemical reactions characteristic of an alloy of iron and carbon.

Carbon steels are low carbon, they are used in the manufacture of nets, rolled products.High carbon steel is used for making tools, blades, so it is more durable compared to low carbon.The higher the carbon content in the alloy, the greater hardness but lower toughness and ductility.And high-carbon alloy excellent withstand dynamic loads, little susceptible to oxidation, wear-resistant and lightweight.Because it is manufactured machine parts, boilers, turbines, pipes, ie
all those components that are subjected to high loads during operation.

Alloy steels are not susceptible to corrosion, so-called stainless steel.In the process for smelting iron-carbon alloy is added alloying elements such as chromium, manganese, tungsten, molybdenum, aluminum, and many others.Each element of the steel reported any new quality, it had not peculiar.Alloying elements are responsible for the crystal lattice of the alloy, its support structure, informing the alloy increased hardness, toughness, refractoriness.With the addition of vanadium, tungsten and chromium receive high speed steel, which has a very high thermal stability.She goes for the manufacture of cutting tools such as drills, perks, taps, cutting blades, etc.

addition of doping to improve the quality of steel used chemical coatings such as chromium plating, galvanizing.Unlike doping when additional substances are used in the smelting of the steel, the coatings are applied on top of the finished part.So made galvanized pipe, nickel-plated, chrome-plated.Coatings are applied to specific parts of galvanic baths, electrochemical or chemical method.Details of this processing are immersed in a special solution.
