Deep cryogenic treatment is a complex science, however it is one that vastly benefits a number of different industries. While it would be impossible to give readers of this page a detailed rundown of every process involved, we feel it is important that you have an overview, so that you can be better informed regarding what we actually do. Of course, if you have any specific questions regarding any aspect of the way in which we work, please don’t hesitate to contact us today.
Perhaps the first thing to understand is this: what exactly is meant by the term “cryogenic”? In answer to this question, it is a term used in the world of physics, and it applies to the freezing of materials at exceedingly low temperatures of below -150°C/-238°F. By exposing metal to this extreme temperature, a number of important changes are made, which are beneficial to people from many walks of life.
The way in which cryogenics works to strengthen ferrous metals (any metals containing iron, such as steel) is to transform a large amount of retained austenite into martensite. As martensite is a smaller and, perhaps more importantly, a harder crystal, the strength of the material is already improved. By exposing the metal to even lower temperatures, further molecules are released. These are called carbides, and they begin to spread out equally over the material, therefore creating an even tighter molecular bond – and this tighter molecular bond ensures a further increase in strength and durability.
Cryogenics is also a useful process for those wanting to strengthen non-ferrous metals, with the most popular of these being aluminium and titanium. This is because the process allows the molecules to gain uniformity within the metal’s structure – something that they aren’t able to effectively do when metal is cast. By creating a uniform structure throughout the metal, it removes any areas that are prone to stress, therefore creating a structure that is able to stand up to the rigours that some applications demand of it.
As can be seen, the process is a complex one, however our expert cryogenicists have an intricate understanding of it and are able to use this knowledge to provide the results you need. We have worked within a number of industries to improve the performance of tools, parts and equipment, so please don’t hesitate to contact us today to find out how deep cryogenic treatment can help you.
