Right from its existence in 16th century, wrought iron has never gone out of market and still has the same demand and features. Wrought iron is not at all distinguished by its looks, but by its working properties and resistance to corrosion. Though there is no visible difference between forged bars and wrought iron, what make wrought iron superior are the effective properties that are most prominent. Wrought iron is soft to build and features a high durability than mild steel. It can withstand any higher heat thereby making it more malleable under the hammer. Most of the world famous historic monuments and sculptures are made up of wrought iron. The foremost specialty in using wrought ironwork is it requires little or even no maintenance. It has been stated in theories that, carbon in steel is responsible for its corrodibility. Therefore, removing the carbon content in steel and iron removes the problem of corrosion. One of the chief reasons of using wrought iron in today’s industry is it includes very less content of carbon in it. While in the manufacture of wrought iron itself, most of the carbon impurities are driven out. Anyhow, these impurities aren’t separated out right away in the first step of manufacturing process. They remain included in the matrix of the iron. It is then exposed to high temperatures and by then the impurities turn to glass which is commonly known as slag. Up to 5% of wrought iron is present in this slag, and it is believed to inhibit corrosion in a number of ways. The oxide layer covering the surface of the iron structure acts as a protective coating that prevents further corrosion. The slag also has additional advantages in relation to traditional forging techniques, particularly fire welding. Wrought iron when heated to a red heat is then hammered into shape, and after shaping it is quenched in oil or water to harden it. Wrought iron has been used for centuries because of its durability and decorative nature. From protecting windows and doors to popular decorative castles, wrought iron has truly served a multitude of purposes. Since wrought iron is malleable, it can be made into all sorts of shapes, especially used in the manufacture of ornamental railings and gates. Wrought iron does not break easily but can be bent a bit under cold temperatures, whereas cast iron and other types of materials easily shatter if beaten hard. Wrought iron’s indoor purposes include the manufacture of wall dcor, candle holders, lamps, chandeliers, fireplace accessories, and a variety of furniture pieces.
