"Coating" the structure of metals at deep cryogenic temperatures

Durability is the most important criterion when defining the quality of a tool steel. Cryogenic tempering of metals is becoming acknowledged as an effective method for increasing durability, or "wear life", and decreasing residual stress in tool steels. The process creates many benefits for steel, including an exceptional increase in durability and wear resistivity, generally exceeding 300% as the greatest benefit. Tensile strength, an increase in toughness and greater stability through the release of internal stresses are also created.

Deep cryogenics (below -300°F­) is creating new applications in science. High temperature superconductors, the super-conducting super-collider, cryobiology, magnetohydrodynamic drive systems for ships and low-temperature physics have all developed recently.

Dry cryogenic processing physically transforms the micro-structure into a new, more refined, uniform substructure, which is stronger.

Deep Cryogenics has enhanced the racing engine parts more durable and even for some instances doubled and tripled their productive life.
Cryogenics temperature occurs abovemolecules change and make all the retained austenite turn to martensite. Dry cryogenic must physically transforms the micro structure into a more refined, uniform substructure.

Cryobiological Inventory Systems

Store samples up to 225 days without replenishing liquid nitrogen

• Compact size stores up to 3600 samples
• Advanced vacuum insulation minimizes liquid nitrogen evaporation

Find the sample you need quickly and efficiently! All Locator systems feature a double-walled, vacuum insulated vessel with a narrow-mouth neck that keeps liquid nitrogen losses to a minimum. Stainless steel racks fit snugly against the wall of the Locator system to hold multiple racks. The rack handles rest in numbered slots for easy identification and retrieval. Each rack has individual storage locations for cryogenic boxes.

Deep Cryogenic treatment of gun barrles and benefits

Guns created from forging and castings cooled at different rates, induce residual stress. Gun barrel are bored and machned which causes stress in the microstructure of the metal. But cryogenically treat gun barrel below -300°F relives the residual stresses.

Cryogenic treatment can be done on tools coated with TiN, TiCN, TiAIN, and TiAICN

The Cryogenic Institute of New England offers custom based cryogenic treatment for tools used in manufacturing industry

Even though coatings such as TiN, TiCN, TiAIN, and TiAICN are already widely used and relatively inexpensive; cryogenic treatment should be kept in mind. Cryogenic treatment can used on tools that have already been coated without causing any problems. Coatings will help keep the tooling sharp and increase wear resistance as will cryogenic treatment.

Deep Cryogenics processing significantly increases rifle accuracy by relieving residual metal stresses in the barrel

The deep cryogenic process for rifle barrels controlled with dry thermal treatment. The material is cooled up to -310°F held for a day then raised to +310°F and slowly returned to room temperature. The dry thermal process prevents rifle barrel from thermal shock.

Deep Cryogenics makes engine parts more durable

Many racers have tried this method by applying with dry ice to heat treatment approximately -120°F to change molecular structure of metal..

It is at cryogenic temperatures (-300°F) that the molecule change, making all the retained austenite turn to marstensite, a more dense, refined mix that is smaller and more uniform than austensite..

Dry cryogenic processing transforms micro-structure into stronger uniform substructure..
