Physical Properties

Grade 316L stainless steel physical properties are listed in the table below such as density, melting point, specific heat, electrical resistivity, elastic modulus (modulus of elasticity), thermal conductivity, etc.

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
