There is no real, discrete temperature at which an oxidation reaction (or any other chemical reaction for that matter) starts.

Instead reaction rates are dependent on absolute temperature and follow Arrhenius equation.

In short this means that at low temperatures (e.g. close to room temperature) reaction rates are usually (but not always) almost infinitesimally small and then increase as temperature is increased. There is however no discrete temperature at which the reaction can be said to 'start'.

To get a better idea of this rate/temperature dependence, chemists will usually perform an Arrhenius plot.
