Since ancient times people have used the procedure of hardening of metal products, which were necessary in everyday life. Whether edged weapons or tools for agricultural work – all required high tensile strength. So people have necessitated the invention of such a process, in which the metal would become harder and ductility it was declined. And a method of processing metal products was found. Hardening steel – such is his name.  To acquire the necessary qualities of the metal in the hardening process undergoes heating and subsequent cooling.

When there was stainless steel, there is a need for improvements in those methods and techniques, which processed metal. Heat treatment began to evolve in new ways, thanks to today hardening steel (stainless) gives the possibility of obtaining new materials of higher quality.

Martensitic stainless steel is a steel which is mainly used in the quenching process. Her usual self – increased hardness, however, it differs in that it prone to brittleness. The use of heat treatment with quick release promotes the increase in viscosity that characterizes this kind of steel as one of the most sought-after metals.

In working with stainless steel rolled distinguishes between the following types of hardening – a global view, when the product is heated up completely, and local, where applicable partial hardening those areas that are needed. In addition, in a process like tempering steel, various methods of cooling. It depends on what brand of stainless steel. Mainly for these purposes, used oil, alkali and salt. Water as a cooling medium is rarely used.

Depending on what product form and grade of the metal applied to the different methods of hardening steel. Distinguish the stepped quenching and isothermal quenching with szamotulska.

The Main parameters of the process are heat (temperature) and cooling (speed). Moreover, the speed with which will cool the steel after being heated to the desired temperature, will affect the results of the school. The main technical challenge of the process is to select the optimum temperature in view of the fact that overheating stainless steel may lose the hydrocarbons that will reduce its strength. In order to avoid residual stress in the inner structure of the hardened metal, you should use additional mechanical processing methods. For example, gradual cooling, where the temperature drop will be gradual. This hardening process is good for making those pieces, which is designed to produce heavy-duty tool.

There is also surface hardening of steel. It does not take much time unlike chemical-thermal treatment, which allows you to automate the process. With this method of performing the process of hardening needed to make your inductor and your selection of the processing mode for each individual part. Surface hardening suitable for the production of parts of the same type (mass production), for example, in the automotive industry.

Thus, for high-quality metal, which would have a combination of strength, toughness and ductility in the required proportions, to apply to the metal a unique process called “hardened steel". Although stainless steel is one of the best materials of our time, however, the technology to improve its quality, has come to us from ancient times.
