ASTM TP 321 Seamless Stainless steel Tube Sch80 Used in Heat Exchanger
Introduction to products:
AISI 321 stainless steel (SS321) is a standard austenitic 18/8 stainless steel grade with the addition of titanium (Ti), which stabilizes carbides against sensitization to prevent intergranular precipitation of chromium carbide when the steel is heated to a temperature within the sensitization range (such as during welding). Remarkably high strength as well as scaling resistance and phase stability set 321 Stainless Steel apart from other similar grades.

| Melting point, °C (°F) | 1400-1425 (2550-2600) |
| Specific heat capacity, J/kg·K (Btu/lb ·°F) | 500 (0.12) at 20 °C |
| Electrical resistivity, μΩ·m | 0.72 at 20 °C |
| Magnetic permeability | 1.02 (Approximate) |
| Elastic modulus, GPa (106 psi) | 193 (28) |

| 22.2 (12.8) at 500 °C (932 °F) | |
| Coefficient of thermal expansion, 10-6/K (μin./in. ·°F) | 16.6 (9.2) at 0-100 °C (32-212 °F) |
| 17.2 (9.6) at 0-315 °C (32-600 °F) | |
| 18.6 (10.3) at 0-538 °C (32-1000 °F) | |
Notes:
10-6·K-1 = 10-6/K
1 Ω·mm²/m = 1 μΩ·m
1 g/cm3 = 1 kg/dm3 = 1000 kg/m3
1 GPa = 1 kN/mm2
1 MPa = 1 N/mm2
other supplement:
