Stainless steel is a ferrous metal as it contains iron. Ferrous metals mostly contain Iron. They have small amounts of other metals or elements added, to give the required properties. Ferrous metals are magnetic and give little resistance to corrosion.
Ferrous metals also have a high carbon content, which generally makes them prone to rust. The exceptions are stainless steel, because of chromium, and wrought iron because of its high pure iron content.26
