process of creating Damascus steel

Damascus steel, also known as damask, very popular in the East.It is produced by melting iron and steel with charcoal in a special chamber with a lack of oxygen.In the process of heating the metal absorbs carbon from the charcoal, and the resulting alloy is cooled very slowly.This gives the material a unique visual pattern.

Forging changes the crystal structure of the substance and the metal takes on a bluish color, by which is known for Damascus steel.This method is very time consuming and requires a high degree of skill in order to maintain the desired temperature at the same level during the entire process.Material obtained in the production process is not enough to create large structures.But it would be enough for it to forge a sword or dagger.This causes the high price of
goods of this type of steel.

Damascus steel factory, known as welded steel, was more popular in the West.At the same time the final product get a lot more with less labor.The process of its production is heating two or more pieces of iron and steel, and then bonding them together.Wherein the workpiece surfaces are softened, while the core remain cool and solid.

Compound surfaces together at high temperature and in the presence of a gas stream to create a sealing interface allows a welded connection.It essentially represents the connection of two metals into one.Further heating of the workpiece and the resulting change in its shape makes it possible to get a damask or Damascus steel.

Properties damask

Besides the beautiful and aesthetic appearance with a pattern on the surface, damask has a lighter and more flexible than ordinary steel.These features are critical when choosing a material for knives.

Although the first record of creating Damascus steel were made in India and the Middle East, the Norwegian blacksmiths were also recognized masters in this matter.They began to create the swords of this material even in the sixth century AD.This five hundred years before the appearance of the first Japanese katana from such steel.

Despite the excellent quality Damascus steel is a relatively inhomogeneous material as compared to the high-metal species.These materials began to be produced in the nineteenth century in Europe, when the most modern methods of processing metals.In the twentieth century, with the advent of nanotechnology, it was invented more advanced materials.However, Damascus steel, and is now quite popular in creating knives.
