You usually replace your pans after 5 years of usage—or even less when you see them peeling. However, some may last longer, depending on the material and how it is made. You can usually check this on your manufacturer’s guide. More often than not, high quality and expensive pans have a lifetime warranty so you don’t have to worry about breaking your bank again for another pan. However, the warranty only applies if it is evident that you maintained the product well.
