Carbon Steel Machining

Carbon steel describes steel or metal alloys that are not stainless. Compared to other specialty hard metals, carbon steel alloys are usually inexpensive and easy to machine. These alloys can include low or high-carbon steels, which are easy to machine and offer high-wear resistance and tensile strength. Both types of carbon steel offer reasonable strength when compared to aluminum, although they do not offer the corrosion resistance provided by stainless steel.

Carbon Steel Machining Considerations

Unless heat-treated to high-tensile or wear-resistant levels, carbon steel is generally easy to machine. As hardness increases, the machinability of carbon steel decreases. When treated, hardness levels can reach up to 60 RC, making the carbon steel not machinable with traditional CNC machining methods. However, Miller CNC partners with suppliers that perform non-traditional machining methods such as grinding, honing, and EDM to increase machining options for your carbon steel components.

While machining carbon steel, difficulties can arise when attempting to achieve fine surface finishes. Carbon steel is generally “soft,” requiring proper cutting strategies to maintain tight dimensional tolerances and surface finishes. Miller CNC has developed optimal machining methods and tooling knowledge to help us achieve favorable material removal rates without compromising the fine surface finish measurements and aesthetics.

Miller CNC Carbon Steel CNC Machining Advantages

We primarily machine high-tensile grades of carbon steel, including 4120, 4140, 4340, 300M, 8620, and more. Many carbon steel grades are heat-treated or case-hardened before finishing to tailor their physical properties to the intended application. Miller CNC can perform carbon steel machining in the form of bar, plate, forging, and casting methods to create machined components including:

• Fasteners
• Fittings
• Manifolds
• Shafts
• Valves
