Steel vs. Stainless Steel: Know the Difference
By Shumaila Saeed || Published on January 2, 2024
Steel is an alloy of iron and carbon, while stainless steel is a steel alloy with added chromium to resist corrosion.
Key Differences
Steel is a versatile metal alloy primarily made of iron and carbon, known for its strength and durability. Stainless steel, however, includes chromium, making it resistant to rust and corrosion, which is absent in regular steel.

The manufacturing of steel involves combining iron with carbon, which enhances its tensile strength and hardness. Stainless steel's manufacturing adds at least 10.5% chromium to the mix, providing a protective layer that prevents rust and stains.

In terms of applications, steel is widely used in construction, infrastructure, and manufacturing due to its robustness. Stainless steel finds its primary usage in environments requiring corrosion resistance, like in kitchen appliances, medical equipment, and automotive parts.

The aesthetic difference is notable; steel often requires coatings or paint to prevent rust, whereas stainless steel boasts a natural, shiny finish that requires less maintenance.

Cost-wise, regular steel is generally less expensive compared to stainless steel. The additional chromium in stainless steel adds to its cost but provides the benefit of increased longevity and low maintenance in harsh environments.

Steel
A variety of iron intermediate in composition and properties between wrought iron and cast iron (containing between one half of one per cent and one and a half per cent of carbon), and consisting of an alloy of iron with an iron carbide. Steel, unlike wrought iron, can be tempered, and retains magnetism. Its malleability decreases, and fusibility increases, with an increase in carbon.
