430 Asta in acciaio inossidabile: Composizione, Performance and Standard Sizes
430 stainless steel rod is a ferritic stainless steel widely used for its good corrosion resistance, magnetic properties, and cost efficiency. It is commonly applied in household appliances, decorazione architettonica, automotive trim, and industrial components where moderate corrosion resistance and good formability are required.
Compared with austenitic grades like 304 E 316, 430 stainless steel contains no nickel, making it more economical while still providing decent oxidation resistance and stable performance in mildly corrosive environments.
Composizione chimica di 430 Acciaio inossidabile
Le prestazioni di 430 stainless steel rod is mainly determined by its chromium-based ferritic structure. The absence of nickel significantly reduces cost while maintaining reasonable corrosion resistance.
| Elemento | Contenuto tipico (%) | Funzione |
|---|---|---|
| Cromo (Cr) | 16.0 – 18.0 | Main corrosion and oxidation resistance element |
| Nichel (In) | ≤ 0.75 | Very low or trace amount (cost reduction) |
| Carbonio (C) | ≤ 0.12 | Improves strength and hardness |
| Manganese (Mn) | ≤ 1.0 | Migliora la lavorabilità a caldo |
| Silicio (E) | ≤ 1.0 | Migliora la resistenza all'ossidazione |
| Fosforo (P) | ≤ 0.04 | Controlla la fragilità |
| Zolfo (S) | ≤ 0.03 | Migliora la lavorabilità (controllato) |
| Ferro (Fe) | Bilancia | Matrice di base |
