Nitriding of steel is done (in electric furnace) at _____________ °C?
Correct answer: A. 510
- A. 510
- B. 1720
- C. 2210
- D. 910
Explanation
Gas nitriding is normally conducted at about 500–550°C, so 510°C is the suitable value. The higher temperatures listed are associated with melting or other high-temperature operations, not nitriding.
