The need for special steels grows every day: today, they need not only "traditional" industries – defense and aviation, but also the construction of (mostly high-rise), engineering and others. Undoubtedly, these products are expensive, because their manufacture requires a significant amount of resources. Nevertheless, the demand will increase further, because the characteristics of the metal are often allowed to drastically reduce material consumption and cost of manufactured products. That these arguments are sometimes crucial to introduce in the production of special steels. What is steel for special purposes? According to the definition of special steel destination – it rolled iron-based, featuring special properties due to a chemical compound, or a special production method, any method of treatment.
This category includes carbon steel: quality construction, tool, curing, cold-punching, etc. In most cases, special steels contain alloying elements – such as manganese, chromium, molybdenum, tungsten, etc., which specially introduced into the alloy to obtain the desired structure, the structure, physicochemical and mechanical properties. Content in steel alloying agents can vary from thousandths of up to several tens of percent. The composition of special steel is the minimum amount of phosphorus and silicon, but because it has a good ability to hot-dip galvanized and flexible and can be processed using a mechanical cutting, and plasma. Production of special steels requires the participation of highly qualified personnel, the use of modern methods of controlled rolling and heat treatment of products, the use of significant amounts of energy. In short, only high technology can provide the specified characteristics of the final product. .
