Prevent rust staining from the quenchant pt. 1

Induction does not promote any appreciable corrosion. However, it is well-established that corrosion intensity increases with increasing temperature (regardless of whether the temperature increase is after induction heating or any other heating means, assuming that the rest of conditions remain the same). Therefore, if selected regions of the heat treated part have different temperatures, then areas at higher temperatures will experience greater corrosion com- pared with areas at lower temperatures.
