Aisi 430 Stainless Steel
AISI 430 stainless steel is a ferritic stainless steel offering good corrosion resistance, excellent formability, and cost-efficiency. Its combination of chromium content and low carbon makes it ideal for appliances, architectural panels, automotive parts, and industrial equipment where moderate corrosion resistance and attractive finish are required.
- Description
AISI 430 is a ferritic stainless steel known for its excellent corrosion resistance, good formability, and cost-effectiveness. It is widely used in appliances, architectural applications, and automotive components where moderate corrosion resistance and attractive finish are required.
Chemical Composition
| Element | Content (%) |
|---|---|
| Chromium (Cr) | 16–18 |
| Carbon (C) | ≤ 0.12 |
| Manganese (Mn) | ≤ 1 |
| Silicon (Si) | ≤ 1 |
