- Nickel
Hint:
Steel is an alloy of iron and carbon
The correct answer is: Tungsten
- Stainless steel is an alloy of iron that contains around 20% Chromium. The Chromium produces a thin layer of oxide on the surface of the steel which prevents further corrosion. Nickel is also present to enhance its structure.
- So Tungsten is not present
