Differences in Properties: Steel vs Iron A Guide By Midwest Steel
What is Iron?
Iron is a chemical element that is very abundant in nature, especially in the Earth’s crust. For millions of years, humans have used iron, which has contributed to the development of civilization and the modern metal production industry.
Pure iron is silvery-white, soft, and brittle. Although it has poor mechanical properties, it has good thermal conductivity and magnetism. However, iron easily oxidizes, forming rust that reduces its applicability and creates unsightly surfaces.
What is Steel?
Steel is an alloy, meaning it consists of multiple elements. The two most important components are iron and carbon. Based on the use, the proportion of elements is different, leading to more than 3,500 types of steel with varied properties. Among these, the four most common types of steel are carbon steel, alloy steel, stainless steel, and tool steel.
Learn About the Differences in Properties: Steel vs Iron
Differences in Strength Between Steel and Iron
Steel is stronger than iron, making it an ideal material for construction and manufacturing. Despite being lighter than iron, steel has a good load-bearing capacity and resists deformation under force.
Corrosion Resistance: Steel vs Iron
Corrosion resistance is a key factor distinguishing steel from iron. Corrosion occurs when metals or alloys deteriorate due to environmental factors like water, air, and soil. While both iron and steel can corrode, steel typically resists corrosion better. Stainless steel, in particular, is up to 200 times more resistant to corrosion than conventional steel.
Durability Comparison Between Steel and Iron
Steels offer better durability than pure iron, hence their ability to take the lack of some contents in its alloy. Iron’s porous structure makes it more vulnerable to weather and environmental damage.
Versatility: Steel or Iron?
Iron or Steel sheets are more versatile than iron as they can be shaped and bent into different forms, including hollow sections. Pure iron is inherently soft and needs to be mixed with carbon and other metals to facilitate casting and forging.
| Property | Steel | Iron |
| Composition | An alloy of iron with carbon and sometimes other elements like chromium. | Pure elemental iron or iron with trace impurities. |
| Strength | Higher tensile strength due to carbon and alloying elements. | Lower tensile strength compared to steel. |
| Hardness | Harder than pure iron, especially with higher carbon content. | Softer than steel, can be dented or scratched more easily. |
| Ductility | Less ductile, especially with high-carbon steel. | More ductile, especially in its pure form. |
| Corrosion Resistance | Often higher, especially stainless steel with chromium. | Poor, rusts easily when exposed to moisture and air. |
| Weight | Slightly heavier due to added alloying elements. | Slightly lighter in pure form. |
| Malleability | Less malleable than pure iron. | Highly malleable and can be shaped easily when heated. |
| Cost | More expensive due to processing and alloying. | Cheaper in pure or raw form. |
| Uses | Used in construction, machinery, tools, automotive, and aerospace. | Limited use, mainly in wrought iron or cast iron products. |
| Magnetism | Magnetic, depending on the type (e.g., stainless steel may be less magnetic). | Highly magnetic in its pure form. |
| Durability | More durable and resistant to wear and tear. | Less durable; prone to rust and wear. |
| Melting Point | Lower than pure iron, depends on alloy composition (~1370–1510°C). | Higher melting point (~1538°C for pure iron). |
