When selecting materials for Lavorazione CNC, fabbricazione di lamiere, and stamping, manufacturability often matters more than ultimate strength. 1006 acciaio al carbonio, with its ultra-low carbon content, is widely favored in production environments where formabilità, weldability, and process stability sono critici.
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. Cosa è 1006 Acciaio al carbonio?
1006 carbon steel is classified as an ultra-low carbon steel, containing no more than 0.08% carbonio. Unlike higher-carbon or alloy steels, it is not designed for high-load structural performance. Invece, 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.
| Elemento | Content (%) | Manufacturing Significance |
| Ferro (Fe) | 99.43–99.75 | Provides a uniform, predictable base material |
| Carbonio (C) | ≤ 0.08 | Enables high ductility, low hardness, excellent weldability |
| Manganese (Mn) | 0.25–0.40 | Improves strength slightly and supports deoxidation |
| Fosforo (P) | ≤ 0.040 | Controlled to prevent brittleness |
| Zolfo (S) | ≤ 0.050 | Low levels preserve ductility and weld quality |
Key takeaway for manufacturers:
Low carbon = soft material + stable forming + minimal welding defects.
3. Mechanical Properties Relevant to CNC & Formare
From a production standpoint, these mechanical values explain how 1006 steel behaves on machines and presses:
