- Ductility: Good, with excellent toughness and the ability to withstand impact loads.
Machinability
Low-alloy steels are generally easy to machine and are considered more machinable than high-alloy steels due to their moderate hardness and strength. They can be processed with standard CNC tools and are often used in milling, turning, drilling, and boring operations. When machining low-alloy steel, cutting speeds and feed rates need to be adjusted to prevent excessive tool wear and ensure a high-quality finish. Lubrication and cooling fluids help reduce friction and heat buildup, extending tool life and improving surface finish.

F.A.Q.
A: Our CNC machining supports a variety of materials, including:
- Metals (e.g., Mild Steel, Low/High Alloy Steel, Stainless Steel, Aluminum Alloy, Brass, Copper)
- Plastics (e.g., ABS, PA/Nylon, POM, PE, PMMA)
- Composites (e.g., G10 (Glass Epoxy Laminate), G11, FR4)
- Other appliable materials
A: Our CNC machining offers exceptional precision, with typical tolerances ranging from ±0.001″ (0.025mm) to ±0.0002″ (0.005mm).
The exact level of precision depends on factors such as the machine, tooling, material, and operator expertise.
A: Our lead time for CNC machining varies based on the complexity of the part, material, and production quantity.
- For prototypes, the lead time can be as quick as a few days.
- For larger production runs, it can take several weeks to complete the machining process.
A: Absolutely!
We cater to both small prototype runs and large-scale production with equal precision.
