How To Add Carbon To Mild Steel

Mild steel is a popular choice for many construction projects due to its low cost and relatively easy-to-work-with properties. However, mild steel has its weaknesses and may not be suitable for certain projects. If you need something stronger, adding carbon to mild steel can give you the strength and durability that you need for your project. Here’s an overview of how to add carbon to mild steel.

The Heat Treatment Process

Adding carbon to mild steel requires a process known as heat treatment. This process involves heating the metal up to a temperature of around 800°C (1,472°F) before quenching it in water or oil. The process may vary slightly depending on the type of compound associated with the carbon being added, but this is basically how it works: when exposed to high temperatures, the mild steel absorbs some of the carbon from the compound and binds it into its molecular structure, introducing new properties and making it stronger than before.

Choosing Your Compound

The kind of compound used will depend on the type of project you have in mind. For example, if you plan on using your reinforced mild steel for machining purposes, then you should use an alloy like manganese sulfide rather than pure carbon, as this will reduce friction between moving parts. On the other hand, if you want your reinforced mild steel to be resistant to corrosion, then aluminium oxide is probably a better choice as it contains both oxygen and aluminium, which can help prevent rusting. Additionally, some compounds are designed specifically for heat treatment and should be chosen depending on your specific needs.

Compatibility Considerations

When choosing a compound for heat-treating mild steel, make sure that it’s compatible with your application by checking what types of metals can be used in conjunction with it. For instance, some compounds may not be compatible with aluminium or brass, while others may require more stringent cleaning procedures before they can be applied safely. Additionally, you’ll want to consider any potential reactions between different metals when deciding which compound is best suited for your project—you don’t want your reinforced mild steel reacting negatively with another component during operation!


Adding carbon to mild steel is an effective way of reinforcing it so that it can withstand more rigorous applications without breaking down or becoming damaged over time. While there are several different compounds available depending on what qualities you need from your reinforced product (such as anti-corrosion or increased friction resistance), all methods involve heating up the metal and quenching it in either water or oil after exposure to high temperatures—a process known as heat treating. Before beginning your project, however, make sure that whatever compound you choose is compatible with all other components involved in order to avoid any unwanted reactions during operation! Ultimately, adding carbon to mild steel is an economical way of improving its strength without breaking the bank!
