What Type of Steel is Best for Your CNC Machined Part?

CNC steel machining is a process that can be used to create a variety of parts for use in a number of industries. There are many different types of steel that can be used for CNC machining, and each has its own advantages and disadvantages. The best type of steel depends on the specific application and desired properties of the finished part. In general, however, high-carbon steels are often used for CNC machined parts because they can be hardened and tempered to achieve a wide range of mechanical properties. If you need a strong, durable part that can withstand high temperatures, then tool steel or stainless steel would be a good choice. If you need a part that is less likely to corrode, then aluminum or brass would be a better option. 

So, The best type of steel for your CNC machined part will depend on the specific requirements of the part itself. Other factors that must be considered when selecting a steel for CNC machining include machinability, cost, and availability. In this blog post, we’ll take a look at the different types of steel and what makes each one unique. We’ll also discuss how to choose the right steel for your CNC machined part.

The Benefits of Steel Machining

CNC steel machining is a process that uses computer numeric controlled (CNC) machining techniques to shape steel into the desired form. This process offers a number of benefits over traditional machining methods, including greater precision, faster production times, and improved safety.

CNC steel machining offers a high degree of precision thanks to the use of computer-controlled cutting tools. This means that parts can be produced with very tight tolerances, which is essential for many applications. In addition, CNC machines can produce parts with complex shapes that would be difficult or impossible to create using traditional machining methods.

Production times are also shorter with CNC steel machining due to the high speed and efficiency of the cutting process. CNC machines can also operate for long periods of time without requiring operator intervention, which further increases efficiency.

Safety is improved with CNC steel machining as well since the process is fully automated. This reduces the risk of operator error and injuries, and also helps to ensure that parts are produced to the correct specifications. Additionally, CNC machines generate very little waste material, which helps to keep costs down and minimize environmental impact.


Overall, CNC steel machining offers a number of advantages over traditional machining methods. The process is more precise, faster, and safer, and can be used to create parts with complex shapes. CNC machining is an important part of the modern manufacturing process and will continue to play a major role in the future.

The Challenges for CNC Steel Machining

It can be difficult to cut and drill, and it tends to produce a lot of chips and swarf during machining. This can make the CNC machining process slower and more expensive than other materials. In addition, CNC machines may require specialised tooling and bits to machine steel effectively. CNC steel machining can be a challenge for even the most experienced CNC machinists. 

There are a few factors that need to be considered when choosing to machine steel on a CNC machine. The first is the hardness of the steel. Harder steels will require more powerful cutting tools and may cause more wear on the CNC machine itself. 

Another factor to consider is the type of steel being machined. Some steels are more difficult to machine than others and may require different tooling or techniques. Lastly, the finish of the part must be taken into consideration. Achieving a high-quality finish on steel parts can be difficult and requires experience and expertise.

Different types of Steels for CNC Machining Compared

There are a variety of different types of steels that can be CNC machined, each with its own set of properties and characteristics. In general, the three most common types of steels used for CNC machining are carbon steel, alloy steel, and stainless steel.

Carbon steel is the most common type of steel used in CNC machining. It is a relatively cheap and easy to work with material that is strong and durable. Carbon steel can be finished with a variety of finishes, including powder coating, painting, or plating.

Alloy steel is another popular choice for CNC machining. It is made by adding other elements to carbon steel to improve its strength, hardness, and resistance to wear and tear. Alloy steel is often used in applications where high strength and durability are required, such as in gears, shafts, and bearings.


Stainless steel is the third most common type of steel used for CNC machining. It is an alloy of iron, chromium, and other metals that gives it a high resistance to corrosion and staining. Stainless steel is often used in food processing and medical equipment due to its ability to resist bacteria and other contaminants.


CNC machining is a popular choice for manufacturing steel components due to the material’s high strength and durability. Steel also offers a good resistance to wear and tear, making it ideal for parts that will undergo heavy use. CNC machining can produce very accurate and consistent results, making it ideal for creating complex shapes or tight tolerances.However, steel can be challenging to work with due to its hardness.
