Like all metals, however, mild steel has its own advantages and disadvantages. This makes it better suited for some applications than others.

If you're considering using mild steel for your next project but are unsure if it's the right choice, don't worry. Clickmetal's metal specialists have created a guide to help you understand the pros and cons of using mild steel, so you can decide if it's suitable for your needs. Keep reading to find out more!

What Are the Advantages of Mild Steel?

1. Ductility

The "mild" in mild steel comes from its lower carbon content compared to other steel types. Mild steel typically contains carbon in the range of 0.05% to 0.25%, which makes it relatively soft and easy to work with using various fabrication methods like cutting, bending, and shaping. This characteristic makes it particularly useful in manufacturing processes where intricate shapes or precise tolerances are required.

2. Weldability

Mild steel's ductility brings another key benefit: it can be easily stretched without fracturing, which is essential for accommodating thermal expansion and contraction during welding without causing cracks. On top of this, its relatively low melting point compared to other metals simplifies the welding process, decreasing the likelihood of overheating or burning the material.

3. Cost-Effectiveness

Mild steel is generally less expensive than other steel types. This is because mild steel contains a lower amount of chromium and other alloying elements like nickel, molybdenum, and manganese compared to other steels, especially stainless. The absence of these alloys makes the production process for mild steel simpler, requiring fewer materials and leading to reduced production costs.

What Are the Disadvantages of Mild Steel?

Despite its versatility and affordability, mild steel does come with some limitations:

1. Low Strength

Mild steel's softness is beneficial during welding and machining, but it comes at the cost of tensile strength and yield strength. This means it can deform or break under heavy loads, making it unsuitable for high-stress applications like beams, columns, or pressure vessels. It's also less resistant to wear and tear compared to other steels, which makes it a poor choice for applications requiring high abrasion resistance, like cutting tools or bearings.

2. Susceptibility to Corrosion

Because mild steel lacks the protective chromium and other alloys found in stainless steel, it corrodes easily when exposed to moisture or harsh environments. This makes it a poor material for situations where corrosion resistance is crucial, such as in marine and chemical processing applications.

3. Low Melting Point

Mild steel tends to become soft and lose strength at relatively low temperatures, typically around 300°C (572°F), compared to other metals. This limitation restricts its use in high-temperature applications like boilers or furnaces, where it can weaken and become susceptible to deformation or failure. In such cases, materials such as stainless steel, heat-resistant alloys, and refractory metals like tungsten and molybdenum are often a better choice thanks to their ability to withstand higher temperatures without losing most of their strength.

Steel is an increasingly popular material in the world of construction, both in residential and commercial buildings. With urbanization and the need for a rapid construction to keep up with demand, steel’s affordability, strength, and durability have made it the go-to material for construction teams building frames. Most steels have to undergo different processes such as annealing, tempering, and precipitation hardening to ensure the steel’s strength, durability, ductility, etc.

Of course, as with any material, there are both pros and cons that need to be weighed up before its use. Here are some of the top considerations that construction and design teams need to think about.

Advantages of steel frame construction

Steel frame constructions offer the following advantages compared to brick, concrete and wooden constructions.

Strength & durability

Structural steel components are lighter and stronger than weight-bearing wood or concrete products. Typical weight-bearing steel fabrication is 30% to 50% lighter than a wooden equivalent. This makes steel frame construction far stronger and more durable than traditional wood framed alternatives.

Ductility

The quality of ductility refers to the feature of steel structures’ stability if exposed to huge force. Steel, in general, does not crack like comparatively brittle materials like concrete. This property of steel permits steel buildings to bend out of shape, or deform without collapse if there is any breakage risk, thus giving a warning to the inhabitants to vacate beforehand. A breakdown for the steel structures neither happens overnight nor a steel structure rarely can collapse. That is why steel structure buildings are less affected by earthquakes. In brief, a steel structure will give you time to get out of it, in case of the threat of a sudden collapse.

Easy fabrication in different sizes

Steel studs are available in a variety of sizes and can be fabricated in order. This means they can be customized to bear specific loads in buildings of all different types and sizes.

Fire resistance

Steel frame constructions are highly resistant to fire, reducing the fire risk to a building and retarding the spread of a fire should one occur. Special flame retardant coatings act to increase this property of structural steel.

Moisture & weather resistance

Structural steel can have good moisture-resistant properties, depending on its carbon content. Hot zinc coating and extra powder treatments for enhanced rust resistance will make a structural steel component even more immune to the effects of water – an important consideration for components exposed to the weather.

Disadvantages of steel frame construction

• Steel is an alloy of iron. This makes it susceptible to corrosion. This problem can be solved to some extent using anti-corrosion applications.
• It has high maintenance costs as it has to be painted to make it corrosion-resistant
• Buckling is an issue with steel structures. As the length of the steel column increases the chances of buckling also increase.
• Steel has a high expansion rate with changing temperatures. This can be detrimental to the overall structure.
