Types of steel, strength and durability

In construction, engineering and manufacturing, steel is a key material because of its versatility and strength. It is one of those materials that can be found in almost everything around us, from skyscrapers to household appliances. But not all steels are created equal, and choosing the right type of steel for each project is critical.

There is a wide variety of steels, each with its own characteristics that make it ideal for certain applications. Some are stronger, others are more durable, and each is better or worse for certain conditions. Understanding these differences and knowing which one is right for what you need can make a big difference in the end result of a job. That’s why it’s important to understand which type of steel is best for your needs before making a decision.

The UNE 36010 standard

The UNE 36010 standard is a technical regulation that covers the different types of steel used in areas such as construction and manufacturing in Spain, defining requirements and specifications. It was created by several key institutions in the steel world in order to properly identify the different types of steel.

This standard covers aspects such as chemical composition, mechanical properties, manufacturing processes and the tests required to guarantee the quality of the steel. Compliance with UNE 36010 is therefore essential in order to ensure that the materials used in construction and manufacturing meet the safety, durability and resistance standards required by Spanish regulations.

Strength and durability of the main types of steel

Steel is a fundamental material in a wide range of industries, from construction to machinery and tooling. Its popularity lies in its unique combination of strength and durability, attributes that vary depending on the type of steel used.

Pure steel

Also known as basic steel, this is steel in its pure state. Its strength depends primarily on the carbon in its composition. It usually contains iron, and a percentage of carbon that can range from as little as 0.3% up to 2.14%.

304 Stainless steel

As its name suggests, this steel is characterized by its high resistance to corrosion and oxidation. Thanks to its chromium and nickel content, 304 stainless steel is widely used in environments where exposure to moisture and corrosive agents is constant, such as in the food and medical industries and in outdoor applications. In addition, its high durability and ease of maintenance make it the leading option for a wide range of products, from cookware to architectural structures.

Carbon steel

One of the most common and versatile types of steel, this is characterized by its variable carbon content, which can significantly influence its mechanical properties. The higher the carbon content, the greater the hardness and strength of the material, but this also makes it more brittle and less ductile. Carbon steel is used in a wide range of applications, from manufacturing tools and structural components to everyday products. Its durability and its ability to be heat treated in order to improve its properties make it indispensable in many industries, especially construction and automotive.

Corten steel

Corten steel also is highly resistant to corrosion because its components include copper, nickel, chromium and phosphorus. These elements impede deterioration by corrosion without negatively affecting its mechanical properties. Compared to stainless steel, Corten is more resistant to wear and tear, and is mainly used in the manufacture of warehouses, buildings, fences, bridges, lampposts and other street furniture.

Galvanized steel

In this case, the steel is coated with zinc, creating a protective outer layer that resists corrosion. This process improves the durability of the steel, making it ideal for applications in environments where rust is a problem, such as exposed structures, pipelines and building components. The zinc acts as a physical barrier and also provides cathodic protection, meaning that even if the zinc layer is damaged, the underlying steel remains protected from corrosion.

Rebar

A typical type of construction steel is in the form of rolled reinforcement bar, which is appreciated for being easy to cut and bend. This versatility in handling makes it a popular choice in a variety of applications, as it can be adapted to different shapes and sizes according to the specific needs of each project. Its ability to be handled without complex tools makes it ideal for use in reinforced concrete structures, but it is also used in beams, roofs, walls, tunnels, bridges and other elements that require high precision and strength.

How to choose the right steel?

Want to ensure the durability and strength of your project? The selection should be based on an accurate assessment of the conditions that the material will need to endure, including the loads it will be under and the risks of corrosion, wear and tear, and other environmental factors. For example, an architectural structure in an inland location will not have the same requirements as one near the coast, where the weather and the sea can more easily corrode and rust the metal.

A steel with the right mechanical properties will ensure a longer service life and optimum performance, decreasing the need for repairs or replacement. Carefully selecting the material will ensure that the structure or component will maintain its integrity and functionality over time, even under demanding conditions. Choosing a steel with the right strength and durability ensures that the initial investment in the material is justified because of its longevity and superior performance. This not only improves safety and operational efficiency, but also reduces the costs associated with maintenance, repair and replacement. A material that combines high mechanical strength and durability can be the key to the success of any project that requires sustained performance in demanding conditions.
