CNC Machining In Steel
Both alloy steel and tool steel are steels. Alloy steel has good toughness with fatigue resistance and is inexpensive.
Tool steel is a metal alloy with exceptionally high hardness, stiffness, and abrasion resistance and is commonly used in the tool industry.
Custom Machining in Steel
Steel is a general term for iron alloys with carbon.
It is a cost-effective material and is easy to machine and weld.
In contrast to other machine shops, we can provide a full range of precision steel parts manufacturing services, including CNC machining, CNC turning and CNC milling.

Surface Finish for Steel Parts
Steel is a material that is susceptible to be oxidized and It will rust over time, therefore the manufactured parts require proper surface finishing to avoid corrosion.
Electroplating: Carbon steel can be electroplated, such as galvanized or nickel plated, to improve its corrosion resistance.
The process of electroplating deposits a thin layer of metal film on the surface of the part.
Powder coating: Powder coating creates a protective layer of approximately 0.1-0.3 mm in thickness, which improves its corrosion resistance.
Carburizing: Carburization is used to improve its hardness and wear resistance.
Cost-saving Advice
Steel is one of the cheapest materials for metalworking. However, unnecessary machining costs should also be avoided.
- Material Selection: Steel is available in a wide range of grades and the appropriate material should be selected for the specific application. If high strength alloy steel is used where low carbon steel could have been used, it will obviously add additional cost.
- Optimize the setup: Material costs often account for only a small percentage of the total cost of a custom steel part, while machining costs account for a larger percentage, so it is more important to focus on optimizing the machining process in order to achieve a significant reduction in manufacturing costs by completing the entire machining process with as few setups as possible.
