Basics About Colorado Steel Companies

By Odessa Edwards


Steel is an alloy made from of iron and other compounds like carbon. There is normally a primary alloying compound which is mixed with the iron. Elements that can never lack in the alloy are manganese, sulfur, phosphorus, carbon, and traces of aluminium, nitrogen, and oxygen. Alloying compounds that are added purposely to alter the properties of Colorado steel include chromium, boron, nionium, vanadium, chromium, and molybdenum.

Carbon and other elements are applied to boost hardness, which stops displacement of the iron atom crystal structure. The amount of additional compounds added regulates properties like hardness, ductility, and tensile strength. Even though steels have been manufactured by blacksmiths for numerous years, its use changed into large scale after effective and better techniques of production were created. This happened in the seventeenth century.

During 19th Century, the development of Bessemer process allowed production of the metal on large scales reducing the cost of production. This reduced the price of steels greatly. Further refinement in production processes such as use of BOS, basic oxygen steelmaking raised quality and reduced the cost more. Presently, this metal stands among the most plentiful materials in the world with over 1.2 billion tons being generated each year.

After iron ore is smelted through commercial processes, the composition of carbon within the structure is always more than it is needed. To change the ore into steel, the quantity of carbon need to be decreased and other substances added as appropriate. The subtraction and incorporation of elements is done when the ore in form of liquid. The liquid is continually cast into long slabs or ingots.

In Colorado, carbon steel accounts of about ninety percent of all productions made per year. Stainless and surgical stainless versions of the alloy contain about eleven percent of chromium, often mixed with nickel, to be able to resist rusting. Others are also magnetic while others are not. Those that are resistant to corrosion are abbreviated as CRES. Tools steels are mixed with higher amounts of cobalt and tungsten or other compounds to raise hardness to maximum.

Tool steels find use in making tools like axes, hedge cutters, iron cutters, and drills among other instruments which need durable and sharp cutting edges. They may resist very hot temperatures without losing form. Other types of these materials include weathering, manganese, galvanized, dual-phase, transformation induced, Hadfield, eglin, and maraging steels. Manganese or Hadfiels steels contain up to fourteen percent of manganese. If they are abraded, they create a hard skin which can resist wearing.

Steels have many applications in various fields such as construction of buildings, roads, railways, and appliances among others. Most contemporary structures like bridges, airports, skyscrapers, and stadiums get support from understructures that are made of iron and steels. Even structures that have concretes need reinforcement from this material. Other major fields of application include mining, aerospace, offshore construction, mining, pipeline transport, shipbuilding, armor making, and white goods.

Colorado steel industry stands among the most enhanced on the globe. It has a big capacity that enables it to process several thousands of tons of steels yearly. The end materials are utilized locally whereas some are exported to other nations for income.
