Rate of reaction depends on magnitudes of factors such as how high the temperature, acid concentration and internal stress from abbrasion and bending. The name is just a list of factors but not a series like metal reactivity series. If more than one factors exist, all of them increase rate of corrosion but not one first then the next. Just imagine that immerse an iron plate into an acid bath. When we heat the bath, iron corrode faster than either only heat it or only immerse it in acid.
