Why Choose Steel for CNC Machining?
Steel, primarily an iron-carbon alloy with up to 2% carbon and optional alloying elements like chromium or nickel, is the backbone of modern engineering due to its remarkable strength-to-weight ratio and adaptability. It outperforms many metals in load-bearing scenarios, providing a cost-effective alternative to exotic materials while maintaining reliability in extreme conditions. Compared to softer alloys like aluminum, steel’s higher hardness enables longer-lasting parts but demands optimized machining to manage tool wear and heat.
High Strength and Hardness
Withstands heavy loads and impacts, ideal for structural and mechanical components.
Verschleißfestigkeit
Excels in abrasive environments, reducing downtime and replacement needs.
Vielseitigkeit
Easily heat-treated for tailored properties, from ductile to ultra-hard.
Kosteneffizienz
Abundant and recyclable, offering excellent value for high-volume production.
Corrosion Options
Alloyed variants like stainless steel provide protection in harsh settings.
Our CNC expertise harnesses these traits to create parts with precise geometries and minimal defects, surpassing casting or forging in speed and accuracy for complex designs.
Steel Material Properties
Steel alloys are engineered by varying carbon content (0.05–2%) and additives, customizing traits for specific demands. Typical properties include:
- Density: 7.8–8.0 g/cm³, delivering robust yet manageable weight.
- Hardness: Rockwell B 70–100 (up to C 60 in tool steels), balancing toughness and edge retention.
- Tensile Strength: 400–2,000 MPa, scalable via grade and treatment.
- Elongation: 5–50%, supporting formability in low-carbon types.
- Maximum Service Temperature: Up to 1,000°F in heat-resistant alloys.
These qualities position steel as a staple for parts needing superior mechanical performance and environmental adaptability.

Yes, CNC excels at steel with robust tooling and cooling, handling everything from milling to turning for precise, repeatable results on complex parts.
Carbon steel prioritizes raw strength and affordability but rusts easily, while stainless adds chromium (10%+) for corrosion resistance at a higher cost and machinability challenge.
Essential, especially for stainless or alloy steels, to dissipate heat, prevent galling, and extend tool life—high-pressure systems are standard in our operations.
Higher density increases weight and machining time versus aluminum, plus potential warping from heat treatment; however, its strength justifies use in demanding roles.
