The Origin he Origin of of Cr Cryogenics ogenics Greek Cryo – Cold Genics – Born Of Processing at temp below -190°C Cryogenic processing was developed by Aerospace Industry.
Deep Contr Deep Controlled olled Cr Cryogenics ogenics This is a technology where everything we process gets frozen at ultra low temperatures of -193 ° C. Several different time/temperature profiles depending on variables like type of material, maximum wall thickness and total mass being processed. Then everything is held down at temperatures of -193 ° C for 12 - 48 hours followed by gradual ascend and tempering.

Temper emperatur ture Contr e Control ol We have pioneered a controlled deep cryogenic process wherein the cooling of the material was very gradual eliminating thermal shock For optimum and consistent results the temperature changes must be controlled exactly. Our PLCs can duplicate the optimal cooling curve exactly time after time after time.
The Ef he Effect ect on Steels on Steels Retained soft Austenite is nearly completely converted to harder, abrasion resistant MARTENSITE (99.7%). Formation of ETA carbides & secondary carbides & uniform distribution in the martensite matrix Reliving of Stresses Denser & Homogenous molecular structure supported by eta carbides, reducing the possibility of micro cracking, fractures and chipping

The Benefits he Benefits Increased Abrasion resistance-wear resistance Increased Strength and toughness but reduction in brittleness Increased Impact strength Increased fatigue limit Higher heat dissipation property Wear is uniform, thus material to be removed while grinding is lesser to renew the edge Reduction in downtime One time , solid , irreversible process
Per ermanent manent Pr Process ocess A very important benefit of our method is that items only have to be processed one time. This is not a surface treatment. It is a core treatment where the whole mass is treated - and unlike surface treatment - regrinding or resharpening does not nullify the benefit. This is a permanent, irreversible process. So, material have to be processed once and have the same benefits every time you have them reground or re-sharpened.
The Benefits he Benefits Cost savings In today’s highly competitive and quality conscious global market cryogenics enhances tool life, reduces wear and machine downtime - resulting in cost savings. Manufactured Products of better quality
Industr Industrial ial Applica pplications tions Cutting tools – turning, milling, drilling, taps, reaming, Hobbing tools – Hobs, Shapers, Shaver cutters Forging tools – dies for hot and cold forging Press Tools – Dies, punches for blanking, punching, shearing & other operations Carbides – tools, inserts, components High precision & accuracy parts – guides, gauges, shafts & other industrial spares Helps Lower Manufacturing Costs
Limita Limitations tions Steels need to have a good quality heat treatment prior to cryogenic treatment (Cryogenics is supplementary to heat treatment and not a replacement to it.) Cryogenics will make a good tool better, but cannot make a bad part good.
