Stainless steel mainly resists rusting because of the presence of which element?

Explanation

Stainless steel contains chromium, typically at least ten to twelve percent, which reacts with oxygen to form a thin, invisible, self-healing protective layer of chromium oxide on the surface. This layer prevents the underlying iron from rusting, even when scratched, since the layer reforms when exposed to oxygen again. This is why stainless steel is widely used for kitchen utensils, surgical instruments, and appliances. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
