| Abstract Scope | In recent years, cryogenic treatment has been applied to improve properties of the steels in various industries. A common type of cryogenics is deep cryogenic treatment (DCT), where steel is subjected to temperatures below -160 °C. DCT has been reported to change properties of steels such as corrosion and wear resistance, hardness, toughness, better machinability etc. In addition to the beneficial changing of properties, DCT allows also replacement of 2-3 cycles of tempering, which reduces production costs.  This study had taken under consideration a group of selected steels (under same DCT conditions), which are commonly used in various industries. Selected groups of steel were systematically investigated for the influence of DCT on their microstructural, mechanical, and tribological properties. The study provides systematic  data  of  DCT influence  on  the  properties  of  selected  steels, showing  that  DCT  is evidently an effective  method  for enhancing properties of materials used for industrial applications. |
