Cryogenic Metal Treatment
Imagine a 50% or (>) Greater Savings in Service, Repair and Replacement of Metal Parts while maintaining Greater Dimensional Stability and Thermal Dissipation thus allowing Metal to become Stronger and More Wear Resistant.
That is just the Beginning of what CryoHeat Metal Treatment can do by Relieving Stress in the Entire Molecular Structure. Combine this with our Isotropic Micropolishing (accurate to (<) less than .00001 of an inch) and Greatly Increase Horsepower due to Less Friction and Wear while Extending Longevity of Metal parts over 250%!
The Research Behind the CryoHeat Process on 440C Bearing Steel
This research focuses on the influence of shallow and deep cryogenic treatment on the mechanical properties of AISI 440C bearing steel. Hardness of this material is increased by 7% when subjected to our CryoHeat treatment; and by 4% for Shallow Cryogenic Treatment (SCT) compared to the Conventional Heat Treatment (CHT). ‘ImageJ’ software has been used to analyze the optical microscope image of the conventional and cryogenic treated samples to estimate the retained austenite percentage. The retained austenite percentages of these samples were 29%, 8% and 5.7% for the conventional, shallow cryogenic and CryoHeat treated samples respectively. CryoHeat samples show relatively higher hardness than CHT samples due to higher conversion of retained austenite to martensitic structure. CryoHeat samples also show minor increment in hardness when compared to SCT. CryoHeat and SCT samples show improved hardness by 7% and 4% than that of the CHT sample. Fractography analysis of the cryogenically and conventionally heat treated bearing steel were performed using Scanning Electron Microscope (SEM). SEM analysis clearly indicates the formation of flat facets in SCT specimens and micro cracks in CryoHeat specimens.
The CryoHeat Proprietary Process
CryoHeat Metal Treatment provides huge performance gains to metal objects by completely stress reliving the metal. This promotes stronger metal that is more wear resistant, holding greater dimensional stability and capable of dissipating thermal temperatures much easier. CryoHeat has a proprietary process for all different types of metals and they are custom tailored for each application.
- Greater strength
- Better wear resistance
- Reduced thermal temperatures
- Reduces friction
- Reduces surface roughness
- Relieves microscopic stress fractures
- Refines the molecular grain structure
- Allows the machining of parts to tighter tolerances
- Increases dimensional stability on critical components
- Increases component durability and greater longevity
- Promoting a significant savings on valuable repair time and parts replacement
- 2 to 4 times the service life and 20 – 50% stronger metal.
CryoHeat guarantees about 50% savings or more after the treatment; saving in service, repair and replacement of metal parts.
Textural Stress – Arises because of microscopic inhomogeneties in a metal.
Body Stress – Stress created or produced by an external load and contingent body stress when the load is removed.
Residual Stress – The Remains after a load is removed and clearly seen as the retention of stress cracks. It is impossible to cold work steel without creating stresses on the metal. Most common major stress is caused in machining or altering the parts by any form of metal removal. Grinding can produce temperatures in excess of 1650° F. This produces great amounts of surface stress.
The best and most complete way to remove built up stresses from heat treating and manufacturing is through the use of cryogenic temperatures at CryoHeat Metal Treatment. A properly done Deep Cryogenic Treatment will ensure stress relief. The CryoHeat process will never change the color of the metal in any way, as it will change with a heat treatment. CryoHeat Metal Treatment performs cryogenic processing by simply allowing the molecules to realign in a uniform like fashion. This releases any stored energy that may be trapped in the object. This in turn increases strength & toughness within the object as it relaxes back to its proper positioning. The molecules are now working in an orderly and uniform fashion with one another. There are also changes happening on the surface of the material. The gaps along the surface are reduced and are in a more uniform state tightening the Lattice Sphere.
Deep Cryogenic Treatment done in a controlled environment with a CryoHeat processor and special proprietary formula is a very viable stress reliever and can also be used where heat cannot. The CryoHeat process will never change the color of the metal in any way, as it will change with a heat treatment. It can be used prior to; during or after machining of materials. It is a thorough stress reliever all the way through and not just an exterior stress relief as is the case with shot and laser peening and many other ways that only work on the surface until it wears out and still has insufficient material below. During the CryoHeat process there is also a precipitation of fine extra carbides throughout the metal, this is in addition to the larger carbides already present in the ferrous metals. These fine carbides increase the bond within the molecular structure of the metals; which in turn increases wear resistance again.
The Cryogenic process must be strict and deliberate with slow changes in temperatures occurring. CryoHeat is able to perform this within 1° increments. The post temp process must be just as absolute. That is why you need to use CryoHeat Metal treatment. Our company has spent more time doing research and development for many applications.
All Metals and more Gold, Platinum, Titanium, Inconel, Nickel, Colbalt, Crome-Moly, Aluminum, Brass, Copper, Steel, Plastic, Composite Materials, Castings, Forgings, etc… They all can be stress relieved by CryoHeat Metal Treatment; properly, slowly and deliberately enough to allow for molecular realignment and no redistribution of, or creating of, more stresses by rapid temperature fluctuations. WE GUARANTEE IT!!!
Less friction, promoting less heat & wear
