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. 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. Mechanical Properties.
Grade 321H is a modification of 321 with a controlled higher carbon content, to provide improved high temperature strength. A limitation with 321 is that titanium does not transfer well across a welding arc, so is not usable as a welding consumable.
