Cryo Rotor Pair, Front and Rear

Nitro Blast Cryogenically Treated Rotors.

What is Nitro Blast cryogenically processed brake rotors and when do we recommend you purchase these rotors.

Cryogenic processing is a cutting edge scientific process where metal (and some plastics) are treated to improve wear and life by as much as 300%.

The process starts with gradually freezing the brakes to -300F over a 12 to 16 hour period in a liquid nitrogen filled cyro-processing machine (see above picture) at Control Thermal Processing Inc. We have selected Control Thermal Processing Inc as our exclusive cryogenic processing partner due to their long, successful track record in treating automotive parts for race team?s country wide. Please visit their website at www.metal-wear.com .for a comprehensive insight into the science of cryogenics. The 2nd step is to gradually ramp up the temperature back to room temperature usually this cycle last for 8 to 14 hours. The 3rd step is the metal tempering phase or as commonly referred as heat treating. This process is very critical, if not done properly the whole cryogenic process will be mitigated. The cycle time for this phase usually lasts 3 hours and the temperatures increases as much as 1100F. The purpose of this step is improving the hardness of the newly formed primary martensite which will be brittle after the cryogenic phase. It must be properly tempered back to increase the hardness. When completed the crystal microstructure of the metal has been altered to enhance wear, reduce abrasion, reduce stress risers and resist metal fatigue.

Power Stop recommends cryogenically processed Nitro Blast rotors for applications such as: cars and trucks used in fleets, or commercial use, towing and the racer. For drivers who have experienced premature rotor wear or rotor warping.

Typically, the cryogenic process will add 5 working days to your delivery time. For certain problematic applications we may have Nitro Blast rotors in stock ready for immediate shipment. The cost increase over standard rotors averages $30 per rotor.
