Stainless steel is an alloy that is highly resistant to rusting. What are its main alloying components that contribute to this property?
Correct: C
Stainless steel is a family of iron-based alloys known for their excellent corrosion resistance. This property is primarily due to the addition of chromium (typically at least 10.5% by mass), which forms a passive, self-healing oxide layer on the surface. Nickel is also a common alloying element, especially in austenitic stainless steels, further enhancing corrosion resistance and mechanical properties.
