CNC Machining Materials for Steel Parts

Steel 1018

Generally referred to as light steel, 1018 is very weldable as well fit to appear solidifying procedures such as carburizing. Once carburized, this product is generally utilized for gears, worms, mold, and mildew parts.

CNC Machining steel 4130

Steel 4130

When contrasted to normal moderate steel, this kind is commonly known as alloy steel due to its increased degrees of alloying components. This alloy includes chromium and also molybdenum as reinforcing aspects. These components significantly boost its mechanical homes. Applications can consist of taps, drills, and also aircraft engine mountings.

Steel 4140

Steel 4140

The properties of steel 4140 and 4130 are similar, but the carbon content has been increased. The extra carbon increases its strength and gives it better hardening properties. Chromium is also added to improve corrosion resistance. Applications for Steel 4140 include thin-walled pressure vessels, spindles, and high-strength bolts.

Steel 4140 PH

4140PH steel is a pre-hardened version of 4140 steel with excellent mechanical strength and hardness properties. Its pre-hardening eliminates the need for post-processing heat treatment. This is ideal if you are concerned that the heat treatment of the part will cause unacceptable deformation of the finished part. Typical applications include shafts, mandrels, and dies.

Finishes and Post-Processing Options for CNC Machined Steel Parts

We offer a wide range of surface finishes applicable to CNC steel.

Nickel Plating —— Carbon steel can be evenly plated with nickel to improve its corrosion and wear resistance. The process is to add a 0.1 mm thick layer of nickel to the surface of the part.

Powder Coating —— Powder coating creates a solid surface finish, typically between 0.006″ (0.1524mm) and 0.012″ (0.3048mm) thick. Since uncoated steel is prone to rust, steel can benefit from powder coating.

Carburizing —— Some steels can significantly improve their properties by carburizing. This process involves injecting additional carbon into the surface of a steel part during machining, increasing its hardness and wear resistance.
