उत्तर
Stainless steel contains mainly iron and carbon along with Ni and Cr.
Explanation:
Stainless steel is an important alloy made primarily of iron and carbon, but it also contains nickel (Ni) and chromium (Cr). These two metals improve the strength, corrosion resistance, and durability of the steel. Chromium forms a thin protective oxide layer on the surface, while nickel adds toughness and resistance to acids and bases.
