While not as well-known as stainless steel, mild steel can still be found across a wide range of industries. It's used in everything from structural beams to household appliances and is popular for its versatility and low price point.
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!
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.
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.
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.
Despite its versatility and affordability, mild steel does come with some limitations:
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.
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.
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.

Before delving into the characteristics of carbon steel, let&#;s first clarify the definition of steel.
Steel is a type of alloy based on iron. Pure iron is brittle and prone to rust, making it unsuitable for industrial applications. To address this, carbon is added to iron along with elements like manganese and phosphorus, to create an alloyed material. The term steel specifically refers to those compositions with a carbon content ranging from approximately 0.02% to 2.14%. In contrast, iron has classified to have below 0.008%. of carbon content.
As the carbon content in iron increases, it becomes harder, but at the same time, it becomes more brittle. While it gets less prone to deformation under force, it also becomes more susceptible to breaking, especially when subjected to sudden impact or forces beyond its tolerance. This is why materials used for machinery and structures need to possess both hardness and strength.
Steel contains just the right amount of carbon to balance hardness and strength in iron.
As mentioned, various other elements like manganese, chromium, and titanium are added to steel to create alloy steel and special steel, each with distinct characteristics. Special steels with features like rust resistance or high-temperature resistance are developed based on specific purposes.
Among the different types of steel, carbon steel refers to the steel that does not fall under alloy steel or special steel. In other words, carbon steel is steel in its natural state, without the addition of specialized elements or processes. Carbon steel is defined by having an elemental content of elements other than iron and carbon that is below specified values. For instance, chromium is limited to 0.3% or less, and titanium to 0.05% or less.
Carbon steel is classified based on its carbon content, resulting in three categories: low carbon steel, medium carbon steel, and high carbon steel.
Low carbon steel refers to materials with a carbon content ranging from 0.02% to 0.25%, medium carbon steel has a carbon content between 0.25% and 0.6%, and high carbon steel contains 0.6% to 2.14% carbon.
