Cast Iron vs Mild Steel – What’s the Difference

Cast Iron vs Mild Steel

When it comes to cooking, especially when using a grill or a smoker, one of the most important decisions is choosing the right material for your cooking surface. The two most popular options available are cast iron and mild steel. But what is the difference, and which one should you choose? In this blog post, we will explore the primary differences between cast iron and mild steel and help you make an informed decision for your next cookout.

Difference Between Cast Iron and Mild Steel

Heat Distribution:

Cast iron and mild steel have different heat distribution properties. Cast iron heats up slower than mild steel but retains heat much longer, making it an excellent choice for slow-cooking dishes such as stews or roasts. On the other hand, mild steel heats up quicker but cools down faster, making it ideal for quick searing of meats such as steaks or burgers.


Regarding maintenance, cast iron requires more attention than mild steel. Cast iron must be seasoned regularly to prevent rust buildup and maintain a non-stick surface. However, mild steel requires less upkeep, and you don’t need to oil or season it. Instead, you can clean it with soap and water and apply a thin layer of oil to protect it from rust.


Both cast iron and mild steel are durable materials that can withstand high temperatures, but cast iron is generally more robust and can last for years with proper care. Mild steel is more susceptible to rust and corrosion, but it can still last long if you take proper care of it.


In terms of cost, mild steel is significantly cheaper than cast iron. This is because it’s easier to manufacture and requires less time and energy. However, cast iron is more popular for cooking because of its superior cooking properties and durability, making it an investment that can pay off in the long run.

Cooking Applications:

Choosing the right material also depends on what you’re cooking. Cast iron is best for slow-cooking food and dishes that require a steady temperature over long periods. This includes stews, casseroles, and roasts. On the other hand, mild steel is perfect for searing and cooking meals such as burgers, steaks, and fajitas over high heat.


Choosing the right material for your cooking surface is crucial for any cookout, and it ultimately boils down to your cooking preferences and what you plan to cook. While cast iron is more popular because of its durability and superior cooking properties, mild steel is a practical and cost-effective option that can still get the job done. So next time you’re debating between the two, keep these differences in mind and choose the one that suits your cooking needs.
