430 Batang Baja Tahan Karat: Komposisi, Performance and Standard Sizes
430 stainless steel rod is a ferritic stainless steel widely used for its good corrosion resistance, sifat magnetik, dan efisiensi biaya. It is commonly applied in household appliances, dekorasi arsitektur, trim otomotif, and industrial components where moderate corrosion resistance and good formability are required.
Dibandingkan dengan nilai austenitik sejenisnya 304 Dan 316, 430 stainless steel contains no nickel, making it more economical while still providing decent oxidation resistance and stable performance in mildly corrosive environments.
Komposisi Kimia dari 430 Baja Tahan Karat
Kinerja dari 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.
| Elemen | Konten Khas (%) | Fungsi |
|---|---|---|
| Kromium (Kr) | 16.0 – 18.0 | Main corrosion and oxidation resistance element |
| Nikel (Di dalam) | ≤ 0.75 | Very low or trace amount (cost reduction) |
| Karbon (C) | ≤ 0.12 | Improves strength and hardness |
| mangan (M N) | ≤ 1.0 | Improves hot workability |
| Silikon (Dan) | ≤ 1.0 | Meningkatkan ketahanan oksidasi |
| Fosfor (P) | ≤ 0.04 | Mengontrol kerapuhan |
| Sulfur (S) | ≤ 0.03 | Meningkatkan kemampuan mesin (controlled) |
| Besi (Fe) | Keseimbangan | Matriks dasar |
