The physical properties of stainless steel at low temperature

1.Thermal conductivity：There is a slight difference in the thermal conductivity of various stainless steels at very low temperatures. But generally, the thermal conductivity is 1/50 of the one in normal temperature. At low temperatures, the thermal conductivity increases by increasing of the  the flux (flux density).

2. Specific heat capacity：At very low temperatures, there are some differences in the specific heat content of various stainless steels

3.Thermal expansion：For austenitic stainless steel, the shrinkage at 80K (relative to 273K) is slightly different.

4.Resistivity：The difference in resistivity between grades is increased at very low temperatures.

5.Magnetic：At low temperatures, the austenitic stainless steel with different material quality magnetic susceptibility to the load magnetic field are different.
