Stainless steel is an alloy primarily composed of iron and chromium, with other elements added to enhance its properties. The table below outlines the typical chemical composition ranges for the main grades of stainless steel.
| Grade Type | Chromium (Cr) | Nickel (Ni) | Molybdenum (Mo) | Other Key Elements |
|---|---|---|---|---|
| Austenitic | 16% - 20% | 7% - 13% | Varies | Carbon, Manganese |
| Ferritic | 10.5% - 17% | - | - | Low Carbon |
| Martensitic | 12% - 15% | - | 0.2% - 1% | Carbon (controlled), Nitrogen |
| Duplex | 21% - 26% | 3.5% - 6.5% | Varies | Nitrogen |
Stainless steel is classified into different grades based on its chemical composition and crystalline structure:
