Difference between Steel and Stainless Steel

Steel is a very popular material . Its use extends to the most varied contexts, firstly because it is cheap and secondly, because it is easily found. In addition, the fact that it is highly resistant makes its use very versatile.  Difference between Steel and Stainless Steel

Steel is often used in construction, but it also has a wide variety of other applications; likewise, this material is not limited to just one type. Do you know what types of steel there are and what is the difference between them?

If you have doubts about it or are simply looking for a little more information to complement what you already know, then keep reading, because below we explain everything you want and need to know about this interesting topic.


Steel is an alloy of metals , which means that it is created by mixing different elements. Its primary base is iron and the second most common that is present is carbon, which contributes more than 2.1% of the weight of this material.

Each manufacturer can vary in terms of their recipe for creating steel, however, to be considered as such, they must meet a series of basic requirements. For example, the base element must be iron and it must contain carbon; since this is how the high characteristic resistance of this material is guaranteed.

Modifying the ingredients of the steel can have a significant impact on its hardness, ductility and strength.

It is widely used in construction, especially in older buildings, infrastructure in general, tools, ships, cars, machines, appliances and weapons.


On the other hand, there is another type of steel, which is stainless steel. This second type has all the properties of the first, however, it is not corrosive; which means that it cannot be oxidized. This is accomplished through a process in which 10.5% or more chromium is added to the metal alloy.

Chromium is highly resistant to corrosion because oxide layers do not build up on it. Once steel is formed and its surface is damaged by exposing it to oxygen, then the layers tend to repair themselves and cover exposed parts in the process.

Finally, it is important to note that despite the name, stainless steel is not entirely “stainless” and can be stained if it is not properly maintained. It has a wide variety of applications, such as knives, forks, spoons, instruments for surgery and other industrial matters.
