Detailed Solution

The above statement is true.
Stainless steel is produced by mixing nickel and chromium with iron. Stainless steel is steel containing at least 10.5% chromium, less than 1.2% carbon, and other alloying elements. They are made because normal steel gets corroded easily. Corrosion is the process in which a substance is gradually eaten up by air, moisture and chemical substances.
