Steel vs. Stainless Steel — What's the Difference?
By Tayyaba Rehman — Published on December 22, 2023
Steel is an alloy primarily of iron and carbon, known for its strength and versatility. Stainless Steel is a type of steel containing chromium, which provides resistance to rusting and corrosion.

Key Differences
Steel, a widely used material in construction and manufacturing, primarily combines iron and carbon in its composition. The proportion of carbon and the methods of processing and treatment can give different types of Steel with varying properties. On the other hand, Stainless Steel is a specialized category within the steel family, formulated with added chromium.
The inclusion of chromium is what distinguishes Stainless Steel from regular Steel. When Steel is exposed to oxygen, it can rust or corrode over time. However, with Stainless Steel, the chromium present forms a thin layer of chromium oxide on the surface, acting as a protective barrier against rusting or staining. This makes Stainless Steel an excellent choice for environments where corrosion resistance is paramount.
In terms of appearance, Steel can take on a darker hue, especially as it oxidizes. Stainless Steel, owing to its chromium content, often has a shinier, more polished appearance. This aesthetic difference makes Stainless Steel a popular choice for kitchen appliances, cutlery, and other decorative applications.
While both Steel and Stainless Steel are renowned for their strength, their areas of application can vary. Regular Steel, being more malleable, is often used where shaping, welding, and crafting are essential. Stainless Steel, with its anti-corrosive properties, finds its place in environments where moisture is prevalent or where hygiene is a concern, such as in medical instruments.
From a cost perspective, Stainless Steel tends to be more expensive than regular Steel. This price difference can be attributed to the addition of chromium and the processes involved in ensuring the anti-corrosive properties of Stainless Steel.
