The main metal that is added to steel to create stainless steel is chromium.

Explanation:

Stainless steel is distinguished by its increased resistance to corrosion compared to ordinary carbon steel. This property primarily results from the addition of chromium, which forms a protective layer of chromium oxide on the surface of the steel. This layer prevents rust and other forms of deterioration from occurring. Typically, stainless steel contains at least 10.5% chromium by weight, which enhances its mechanical strength and toughness, giving it durability in various environments. While nickel, zinc, and aluminum can also be alloyed with steel, it is chromium that defines the major characteristic of stainless steel. Hence, the correct answer is chromium.
