Stainless steel is cheaper than titanium. Even if the price difference between titanium and stainless steel is likely to become smaller, it is most likely that stainless steel will always remain significantly cheaper, especially in the form of alloys where nickel is replaced by manganese and a part of the chromium is replaced by aluminum. Unfortunately, even stainless steel is considered as too expensive by the car manufacturers, despite the fact that when we consider the total cost over the lifetime of the vehicle, with the need of replacing the rusted parts, the cost of stainless steel could have been less (but then customers would have been repealed by seeing higher upfront costs, without knowing how much they will spend on repairs in the future).
