Physical Properties of 321 Stainless Steel
The key physical properties of 321 Stainless Steel include:
Density: 7.90 g/cm³
Thermal Conductivity: 16.2 W/m·K
Electrical Resistivity: 0.72 µΩ·cm
Melting Point: 1400 – 1450°C
Regarding magnetic properties, 321 Stainless Steel is generally non-magnetic, with only minimal magnetic permeability under certain conditions. This makes it suitable for applications where magnetism could be a concern.
Corrosion Resistance of 321 Stainless Steel
321 Stainless Steel offers excellent resistance to corrosion in acidic, sulfuric, and saline environments. It withstands exposure to harsh chemicals, acids, and saltwater, making it ideal for chemical, marine, and industrial applications.
At high temperatures, its oxidation resistance is also superior, preventing the material from deteriorating in environments with elevated heat and aggressive gases. This makes it highly suitable for use in energy, chemical, and other high-corrosion industries.
Chemical Composition of 321 Stainless Steel
| Element | Composition (%) |
|---|---|
| Chromium (Cr) | 17.0 - 19.0 |
| Nickel (Ni) | 9.0 - 12.0 |
| Titanium (Ti) | 5x(C - 0.08) |
| Manganese (Mn) | 2.0 max |
| Carbon (C) | 0.08 max |
| Iron (Fe) | Balance |
The typical chemical composition of 321 Stainless Steel includes:
Titanium (Ti) plays a key role in enhancing the alloy’s stability and oxidation resistance. It forms titanium carbides, which prevent the formation of chromium carbides, ensuring that the material retains its corrosion resistance and structural integrity, even at elevated temperatures.
