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.

Physical Properties

AISI 321 steel physical properties are given in the following lists, including density, thermal expansion, elastic modulus, thermal conductivity, specific heat capacity and electrical resistance.

 

SS321 Physical Properties
Density, g/cm3 (lb/in.3) 7.9 (0.29)
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)
Thermal conductivity, W/m·K (Btu/ft · h ·°F) 16.1 (9.3) at 100 °C (212 °F)
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:
