1004 steel belongs to the AISI 10xx series of plain carbon steels, where the last two digits typically indicate the approximate carbon percentage.
Typical Chemical Composition
| Elemento | Percentage (%) | Funzione |
| Carbonio (C) | Max 0.06 | Provides strength and hardness while maintaining ductility |
| Silicio (E) | 0.10 – 0.35 | Improves strength and elasticity; acts as a deoxidizer |
| Manganese (Mn) | 0.25 – 0.50 | Enhances strength and toughness |
| Fosforo (P) | Max 0.040 | Improves machinability but excessive amounts reduce ductility |
| Zolfo (S) | Max 0.040 | Improves machinability but may reduce toughness |
Because of its low carbon content, 1004 steel remains relatively soft and ductile, which is why it performs well in forming and welding processes.
