Induction imparts a high surface hardness with a deep case capable of handling extremely high loads. Fatigue strength is increased by the development of a soft core surrounded by an extremely tough outer layer. These properties are desirable for parts that experience torsional loading and surfaces that experience impact forces. Induction processing is performed one part at a time allowing for very predictable dimensional movement from part to part.

The depth of hardening is controlled by frequency only.

Correct answer is frequency only.

Voltage is directly proportional to frequency. So by controlling the voltage, we can control the frequency. So the answer is correct.
