Frequently Asked Questions

Is 4140 considered a tool steel?

4140 is a versatile alloy steel often used for tooling and general engineering, but it is not classified as a traditional tool steel like D2 or M2. However, it is widely used for tool holders, molds, and machine parts due to its toughness and hardenability.

How to create steel parts?

Steel parts are created through a combination of processes including CNC machining, EDM, heat treatment, and surface finishing. The process depends on the part's design, material, and application requirements.

What is the difference between D2 and M2 tool steel?

D2 is a high-carbon, high-chromium cold work tool steel known for wear resistance and edge retention, while M2 is a high-speed tool steel designed for cutting tools that require high hardness and red hardness at elevated temperatures.

Do you use precision machines to build custom metal parts?

Yes, we utilize advanced CNC machines, EDM, and precision grinding equipment to manufacture custom metal parts with tight tolerances and complex geometries.
