No idea what this Nitrac / deep frozen process actually does, I read through its explanation as well as Deep Frozen site but still come out totally confused!
The wording is a bit similar to the "Nitriding" process which is commonly used for adding nitrogen into metal for hardening process such as crankshaft. However Nitriding is a heat treatment process rather than a deep freeze process.
Heat treatment for disc is a common hardening method, by repeatly heating up the metal and cooling it via various cooling rate, certain metal characteristic can be achieved, rapid cooling can lead to harden but brittle characteristic, while repeated slow cooling can achieve a soft and elastic characteristic. A heat treatment disc can withstand a wider operating temperature range and resist better to disc warp / deform.
I would go for the "heat treatment" disc as that is a well known & proven process. |
