In corrosive, food-grade, or extreme temperature applications a standard carbon-steel chain won't last due to corrosion or the general elements of the application. This is where stainless steel roller chain is recommended due to the metal composition of the stainless steel. It also has the broadest operating temperature range of any standard "on the shelf" roller chain.
