The heat transfer you are referring to is conduction through the metal. Think of how fast that will happen through ANY thin metal, or even wood or plastic for that matter.
What is much more important here is the convection rate, or the rate at which the heat can transfer from liquid to metal or metal to liquid, and that isn't going to be affected by the metal type (aside from surface finish).
You will not have "VERY bad" heat transfer with a stainless chiller.
