Why Choose Carbon Steel for CNC Machining?
Carbon steel offers exceptional mechanical properties that make it ideal for industrial components:
✔ High Strength & Durability – Withstands heavy loads and stress
✔ Excellent Machinability – Easier to machine than alloy steels
✔ Cost-Effective – More affordable than stainless or tool steels
✔ Heat Treatable – Can be hardened for enhanced wear resistance
✔ Good Weldability – Suitable for fabricated assemblies
✔ Versatile Applications – Used across multiple industries
Common Carbon Steel Grades We Machine:
| Grade | Carbon Content | Properties | Typical Applications |
|---|---|---|---|
| 1018 | 0.18% | Good machinability, weldability | Gears, shafts, pins |
| 1045 | 0.45% | Higher strength, heat treatable | Axles, bolts, spindles |
| A36 | 0.26% | Structural grade, excellent weldability | Frames, brackets, supports |
| 4140 | 0.40% | Alloy steel with chromium & molybdenum | Gears, tooling, machinery parts |
| 1215 | 0.09% | Free-machining steel | High-volume turned parts |
