Check out the Cryo-Processing Advantages Increases abrasive wear resistance

1. Requires only one permanent treatment
2. Creates a denser molecular structure. The result is a larger contact surface area that reduces friction, heat and wear
3. Changes the equipment's entire structure, not just the surface Subsequent refinishing operations or re-grinds do not affect permanent improvements.
4. Eliminates Thermal shock through a dry, computer controlled process.
5. Transforms almost all soft retained austenite to hard martensite.
6. Forms microfine carbide fillers to enhance large carbide structures
7. Increases durability or wear life.
8. Decreases residual stresses in tool steels
9. Decreases brittleness
10. Increases tensile strength, toughness and stability coupled with the release of internal stresses

User Testimonials

It has been observed that the process provides the materials a stronger, denser and more-coherent structure thus increasing the abrasive resistance and thermal and electrical conductivity. For steels, the explanation of the phenomena in Layman's terms is as follows: Super cooling the steel refines the carbides in the steel by expanding the carbide structure to fill any voids in the metal. Then as the higher temperatures return, everything relaxes into where it wants to be thus providing stability to the steel. Every step in the treatment is carefully controlled else the temperature extremes will shock the steel into delaminating.

What happens in Cryogenics?

Cryogenic processing tinkers with materials at the molecular level at Cryogenic stillness resulting in

» Homogenizes the Crystal Structure (Achieved by specially designed advanced ramp-soak time programs)
» Grain Structure refinement (New ultra fine carbide particles are formed which are uniformly dispersed throughout the material matrix.)
» Improved structural compactness (Copper Alloys, Steel alloys) significant effects even felt in such finely processed materials like piano strings, banjo, guitar strings etc. this shows that material characteristics are different even at such small cross-sections which are easily corrected by Cryo-tech) improves high frequency capabilities. Copper electrodes exhibit improvements in service life.)
» Prevents concentrated Heat Built-up (Tools, Carbide tools, ball and roller bearings and tools, turbine blades, combustion, chamber, steel industry automobile industry etc. significantly benefit from this improvement)
» Increases Resistance to Deformation (Copper electrodes exhibit improvements in service life)
» Reduces Deformation significantly (Results in less removal of material for redressing, normal saving in Cryo treated material is between 3 & 5 times)
» Reained austenite is converted to a fine martensite matrix (Powdered metal parts, steel alloys etc.)
» Mechanical Properties like micro-hardness, Tensile Strength etc. are the same across any crosS-section (Unlike other processes, cryogenic processing is a one time process and its effect is through and through)
» Significant improvement in dimensional stability(Helps machineability, very close tolerances obtained, reduced scrap-prior to machining cryogenic processing is carried out in several applications such as in machining of radar domes, cockpit instrument panels, missile parts, special precision bearings etc.)
» Relieves residual Stresses (Cutting tools, punches, dies electrodes, castings, forging, automobile gears, cam shafts, crank shafts, ball and roller bearings, springs, cutters, slitters, slotters, trim knives.)
» Several fold improvement in hot hardness (Turbine blades, ball and roller bearings even in battle tanks, gun barrel, tools, dies, valves, steel industry, combustion chamber, fluidized beds, missile cones, compact disks etc.)
» Significant improvement in material toughness (This process can tinker with material hardness without affecting impact strength adversely
» Binder Materials like Cobalt Nickel and in some cases additives of tantalum, Tungsten or Titanium are advantageousl affected (Carbide inserts, brazed carbide tools etc.)
» Big decrease in the amount of catastrophic shattering (Powdered metal parts)
» Produces stronger, denser parts for better performance and longer service life

Cryogenics - Important Points to note :

Chipping BREAKAGE: Cryo-tech process should not alter the hardness of any heat -treated material. If such changes are noted or chipping or breakage is evident it is strongly advisable to temper the product at the last tempering temperature designed after its heat treatment process. If chipping persists, it is a good idea to repeat the tempering cycle. Call our consultants for advice
Tolerance/Machining: It is strongly recommended that the final grinding/honing/finishing of the product is carried out after our cryogenic treatment. The result is far greater wear -resistance, tighter tolerance, superior cutting edge and longer service life. In fact, the Cryo-Tech process will significantly improve the performance of material previously treated by other methods.
Dimensional stability: Dimensional stability and stress relief are additional benefits of the Cryo-tech treatment. The cryogenic process can significantly contribute to complete stress relief of castings, forging, surface hardened components and more.
Downtime savings: The cryogenic process shows that improvements made in strength, stability and resistance to wear can and will reduce the cost of a product by having loner tool life, less scrap, fewer rejections, and above all, less costly down time.
Regrind Savings: Slower and less sever wear of cutting tool is significant with cryogenic treatment and less regrind is needed to renew the cutting edge. It is important to account the number of regrinds to estimate the correct service life.

Typical Uses of Cryogenics :

» Increase life of tools, products & Stress relieve metals for tear free drawing.
» Produce superior tolerances for steel products, improve surface finish, AND INCREASE service life of forgings and castings.
» Reduce machine downtime, increase productivity and reduce scrap rate.
» Increase Grinding Intervals
» Get the product as close as possible to its absolute design limit.
» Help switch to cheaper raw materials if desired.
