What defines ferrous metal, and provide an example?

Ferrous metal is defined as any metal that contains iron. The presence of iron is what categorizes these metals as ferrous, and they are known for their magnetic properties and susceptibility to rust. Steel and cast iron are prime examples of ferrous metals. Steel is an alloy primarily composed of iron and is valued for its strength and versatility in construction and manufacturing applications. Cast iron, while also primarily composed of iron, has a higher carbon content which gives it unique properties such as castability and durability.

The understanding of ferrous metals is critical in welding and fabrication since the welding process and the techniques used can differ significantly between ferrous and non-ferrous metals. Familiarity with different metal types helps in selecting appropriate welding materials, techniques, and equipment, ensuring structural and functional integrity.
