A
Fe,C
💡 Explanation:
Stainless steel is primarily an alloy of iron (Fe) and carbon (C), with chromium and nickel as key additional elements that provide corrosion resistance. The chromium content (typically 10.5% or more) creates a protective oxide layer, while nickel enhances strength and corrosion resistance. Aluminum, tin, copper, zinc, lead, and magnesium are not primary components of standard stainless steel.
