430 Tige en acier inoxydable: Composition, Performance and Standard Sizes
430 stainless steel rod is a ferritic stainless steel widely used for its good corrosion resistance, propriétés magnétiques, et rentabilité. It is commonly applied in household appliances, décoration architecturale, automotive trim, and industrial components where moderate corrosion resistance and good formability are required.
Compared with austenitic grades like 304 et 316, 430 stainless steel contains no nickel, making it more economical while still providing decent oxidation resistance and stable performance in mildly corrosive environments.
Composition chimique de 430 Acier inoxydable
La performance de 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.
| Élément | Contenu typique (%) | Fonction |
|---|---|---|
| Chrome (Cr) | 16.0 – 18.0 | Main corrosion and oxidation resistance element |
| Nickel (Dans) | ≤ 0.75 | Very low or trace amount (cost reduction) |
| Carbone (C) | ≤ 0.12 | Improves strength and hardness |
| Manganèse (Mn) | ≤ 1.0 | Improves hot workability |
| Silicium (Et) | ≤ 1.0 | Enhances oxidation resistance |
| Phosphore (P.) | ≤ 0.04 | Controls brittleness |
| Soufre (S) | ≤ 0.03 | Améliore l'usinabilité (controlled) |
| Fer (Fe) | Équilibre | Base matrix |
