How much do you know about deep
cryogenic processing and its applications? |
 |
|
Deep Cryogenic Processing Does Two Important Things |
| #1.
It can greatly increase the durability of steels beyond what is obtained from conventional heat-treating. Resistance to wear
usually increases up to 600% and micro-cracking is greatly diminished. |
|
Alloy · Tool · Carbon · Stainless · Carbides |
| #2. It also stabilizes many types of ferrous and non-ferrous metals plus
plastics, eliminating residual stresses that can cause problems during manufacturing or in service. Lesser known benefits include increases in electrical conductivity, changes in vibrational characteristics and higher levels of finish in metals. |

Deep Cryogenics- What is it? |
Edwards Heat Treating uses state-of-the-art, computer controlled equipment to safely process your job. Parts are slowly lowered from room temperature to -300°F, typically at one degree per minute. Parts are left at
this temperature for over 20 hours and then brought to room temperature at the same rate. Finally, most metal parts are tempered at an elevated temperature level according to material composition.Liquid nitrogen is used as the refrigerant. Dry nitrogen vapor is fed around the parts by a convection system. No contact with liquid nitrogen is allowed because of the likelihood of creating harmful stress in the material. Amazing metallurgical things occur over time at these low temperatures. For further information, read In Detail. |

But What About Cutting Tools? |
|
The secret to tool life your tool vendor doesn’t want you to know about! |
Send us your tools, new or used. Obtain 50% to 600% more life,
plus less chattering, more predictable tool failure and greater possible feeds and speeds after “CryoTuning.”M and T series high speed, including cobalt-bearing. Carbide also responds well. Lower cost tools can out-perform the expensive coated tools! Treat coated tools if future grinding is specified. CryoTune affects the tool to its core and is a permanent, one-time process. It is not a coating. For worn tools, CryoTune before grinding and the edge typically comes up sharper. We accept tools in their original packaging. We will process and re-box. Plastic coated tools will be stripped and returned paper wrapped. Consider drop-shipping tools from your supplier to save time! |

Metalworkers, Stabilize Your Work |
|
Consider using CryoTune to remove residual stresses that make holding tolerances a challenge.

Improve High Stressed and Wear Parts |
| Many engineers and designers are familiar with the theory of cryogenic material processing but have no first hand experience designing with it. Using this relatively young technology, it is now possible to design to higher stress or wear levels while maintaining part life, or obtain much more service life at the same stress or wear levels. Along with improving the abrasive wear properties and resistance to micro-cracking in hardened metals, the CryoTune process also stabilizes many types of ferrous, non-ferrous, exotic and plastic materials. Parts that must remain dimensionally accurate for a long time in service must have residual stresses removed. CryoTune or thermal stress relief are the options. We welcome participating in your R & D experiments. For more information, check out CryoTune In detail. |

Aluminum Baseball and Softball Bats |
| Modern, high tech bats can be made more durable with a
CryoTune stabilization treatment. Residual stress from the manufacturing operation can contribute to premature cracking. This stress can be eliminated. You may also notice an improvement in the vibrational characteristics of the bat, and a small increase in the hitting power. The process is gentle to the cosmetics, and normally there is no negative effect on the
grip. Obtain “bat insurance” with
CryoTune. |
|
Golf Clubs |
| Metal head designs of today may benefit from a deep cryogenic stabilization treatment. Subtle residual stresses from the forging, casting, machining and brazing operations can negatively affect the way the club vibrates at the time of ball contact. Shafts may also benefit from the elimination of residual stress. Testing of deep cryogenics on golf clubs (and balls) is ongoing. |
|
Fishing Line and Racquet String |
| Nylon and other plastics benefit from a cryogenic stress removal process (even panty hose!) Residual stress from the manufacturing operation contributes to failure. It may be possible to double or triple the life span of nylon strings and even obtain enhanced vibrational characteristics.
|
Brass musical instruments contain a tremendous amount of residual stress after the forming operation.
This stress affects the vibrational characteristics of the metal.
Unfortunately, soldered and polished  instruments cannot be stress relieved in a heat treating oven. The ability of cryogenic processing to eliminate residual stress in metals is well known by machinists and engineers. The
CryoTune process is very gentle and recommended for fine instruments. Musicians report many positive results after their horns are treated. We hear comments such as better pitch-centering, expanded registers and easier playability with less fatigue after a session.Strings, both metal and plastic, tend to last much longer after being cryogenically stabilized. Residual stress always occurs from the extruding, drawing or winding processes. This stress, which contributes to failure when subjected to repeated forces, can be eliminated. Another reason metal strings fail is from a type of chemical embrittlement. Perspiration from the musician is somewhat acidic, and this acid penetrates the micro-cracks in the wire, causing a premature break. Cryotuning will minimize the formation of micro-cracks (see In Detail section.) Interestingly, the chemical composition of perspiration varies from person to person, which is why some guitarists break strings more often than others! Steel slides, metal capos, guitar bridges and nuts are all candidates for CryoTune. Give your instruments and parts a "CryoTune-up!" |

Amplifiers, Cables, Electronics, Circuit Boards, Motors |
| One of the lesser-known effects of deep cryogenic
processing is that the molecular change can permanently lower electrical resistance in materials and increase conductivity. Some engineers have noticed lower distortion in amplifiers and enhanced performance from wires and circuitry. Motors can become more efficient and some have noticed cooler-running components. Many racing engine builders treat ignition systems, wires and even spark plugs in the interest of maximizing spark at the plug. The cryogenic process is gentle to electronic components; even light bulbs can be treated! Edwards welcomes your R&D experiments. |

It is especially appropriate for parts that should not receive a conventional furnace stress relief, such as assemblies, some plastics and those with important surface finishes.
CryoTune stabilizes most metals including steels, non-ferrous, exotics, nylon and other plastics.
