Treat Metal Parts at
−190°C for Permanent
Performance Gains
Improve wear life, toughness, and dimensional stability of tools, dies, and components through a one-time, irreversible deep cryogenic treatment process — trusted since 1999 in Surat, India.

Process
How Deep Cryogenic Treatment Works
The treatment follows a carefully controlled time-temperature profile. Variables like material composition, wall thickness, and total mass determine the exact profile used for each batch.
Initial Part Assessment
Parts are inspected for material type, wall thickness, coating and mass. A custom time-temperature profile is selected. Dimensional baseline is recorded — changes will be only 5–10 microns.
Controlled Cooling to −190°C
Parts are lowered in precise phases to −190°C using liquid nitrogen. Thermal shock is eliminated by a gradual ramp to prevent stress fractures in complex geometries.
Ultra-low Temperature Soak
Retained Austenite converts to tough Martensite (up to 99.7%). Carbide molecules disperse uniformly. Fine new carbide particles form, relieving internal stresses.
Controlled Return to Room Temperature
Parts are slowly returned to ambient temperature in phased steps — ensuring microstructural changes are locked in without thermal distortion.
Post-temper (where applicable)
Certain steels and carbides benefit from a gentle post-temper, further stabilising the Martensite structure and reducing residual brittleness.
Applications
What Can Be Treated
Any ferrous or non-ferrous part that undergoes wear, fatigue, or thermal stress is a candidate. Coated parts (TiN, TiAlN) can also be processed without losing coating integrity.

Benefits
What You Gain from One Treatment
Every benefit is retained even after regrinding — because the entire bulk of the material is transformed, not just the surface.
Increased Wear Resistance
Uniform carbide dispersion dramatically reduces surface wear under friction.
No Change in Hardness
Tougher, not harder — less brittle without being over-hardened or prone to chipping.
Uniform Molecular Structure
Parts can be machined to closer tolerances with less scrap and distortion.
Greater Impact & Fatigue Resistance
Improved resistance to shock loading and cyclic fatigue in demanding applications.
Better Heat Dissipation
Materials dissipate heat more efficiently — enabling higher cutting speeds.
Corrosion Resistance
Micro-surface smoothing reduces oxidation pathways and chemical attack.
Permanent — One Treatment Only
Benefits survive regrinding. Treat once and benefit through the entire service life.
Significant Cost Savings
Longer tool life + fewer regrinds + less downtime = measurable ROI per batch.
