I copied this from the AC website, they're saying the non stick will last...
How long is the warranty on the All-Clad non-stick surface?
Following the All-Clad Care and Use instructions, the non-stick surface will last the lifetime of the pan.
* All-Clad’s non-stick products feature a state-of-the art system rather than a simple coating. The non-stick on All-Clad is actually a reinforced process. The surface of the substrate is blasted with an abrasive, which prepares the surface for better adherence. White hot particles of stainless steel are then sprayed onto the surface. Once these particles cool and harden, they become part of the surface of the substrate, and form a series of "peaks and valleys". The first coat of non-stick is then applied, settling down into the valleys. A second coat of non-stick is then applied filling in all of the valleys and covering the peaks, forming an even surface for cooking. The coatings are permanently bonded to the surface for extreme durability.
