What is Precision Carbon Steel?
Precision carbon steel refers to carbon steel materials manufactured with tight tolerances, smooth surface finish, and stable mechanical properties.
These steels are specifically designed for applications where accuracy, consistency, and surface quality are critical.
Key features include:
- Tight dimensional tolerances
- Excellent surface finish
- Uniform mechanical properties
- Suitable for machining, forming, and fabrication
Technical Properties
| Product | Tensile Strength | Yield Strength | Elongation | Hardness | Surface Finish |
|---|---|---|---|---|---|
| Bars | 400–600 MPa | 250–400 MPa | 20–25% | 120–180 HB | Smooth / Precision ground |
| Tubes | 350–550 MPa | 240–380 MPa | 18–22% | 110–170 HB | Bright / polished |
| Sheets | 400–600 MPa | 245–400 MPa | 20–25% | 120–200 HB | Smooth / milled / polished |
