When selecting materials for CNC обработка, изработка на ламарина, и щамповане, manufacturability often matters more than ultimate strength. 1006 въглеродна стомана, with its ultra-low carbon content, is widely favored in production environments where оформяемост, Заваряване, and process stability са критични.
This article examines 1006 carbon steel specifically from a manufacturing and process-engineering perspective, helping CNC shops, sheet metal fabricators, and stamping manufacturers determine when and why this material is the right choice.
1. Какво е 1006 Въглеродна стомана?
1006 carbon steel is classified as an ultra-low carbon steel, containing no more than 0.08% въглерод. Unlike higher-carbon or alloy steels, it is not designed for high-load structural performance. Вместо това, it is optimized for:
Cold forming and bending
High-volume stamping
Welded assemblies
Cost-sensitive manufacturing
For CNC and fabrication shops, 1006 steel is often selected not for strength, but for process reliability and ease of production.
2. Chemical Composition and Manufacturing Impact
The simplified chemistry of 1006 steel directly explains its behavior in machining and forming operations.
| елемент | Content (%) | Manufacturing Significance |
| Желязо (Fe) | 99.43–99.75 | Provides a uniform, predictable base material |
| въглерод (° С) | ≤ 0.08 | Enables high ductility, low hardness, excellent weldability |
| Манган (Мн) | 0.25–0.40 | Improves strength slightly and supports deoxidation |
| Фосфор (П) | ≤ 0.040 | Controlled to prevent brittleness |
| Сяра (С) | ≤ 0.050 | Low levels preserve ductility and weld quality |
Key takeaway for manufacturers:
Low carbon = soft material + stable forming + minimal welding defects.
