This also depends on the main construction material of the sauce and how durable it is. Ideally, the most durable type of saucepans should be the cast iron and enameled cast iron saucepans. These can survive heavy use and abuse for decades and still look pretty decent with minimal care. On the other hand, a ceramic and granite-coated aluminum saucepan will only last for anywhere between 6 months to 3 years depending on the thickness of the coating material.
