General physical properties of stainless steel patch fittings 
Ferritic stainless steels with high chromium content have low densities, austenitic stainless steels with high nickel content and high manganese content have high densities, and at high temperatures the density becomes smaller due to the increase in the inter-gauge spacing.

Thermal conductivity: The thermal conductivity of all types of stainless steel varies slightly at very low temperatures, but is generally about 1/50 of the thermal conductivity at room temperature. The thermal conductivity increases with increasing magnetic flux (magnetic flux density) at low temperatures. (bottom glass door patch fittings)
Specific Heat Capacity At very low temperatures, there are some differences in the specific heat capacity of various stainless steels. The specific heat capacity is greatly influenced by the temperature, and the specific heat capacity at 4 k can be reduced to 1/100 or less of the specific heat capacity at room temperature.
Thermal expansion: For austenitic stainless steels, the shrinkage (with respect to 273K) is slightly different for 80k. The nickel content has a certain influence on the shrinkage. ( Glass Door Corner patch fittings)
Resistivity: The difference in resistivity between the grades increases at very low temperatures. Alloying elements have a large influence on the size of the resistivity.
Magnetic: At low temperatures, the mass susceptibility of austenitic stainless steel differs depending on the material. There are also differences in the content of different alloying elements. There is no difference in the magnetic permeability of different brands.
Elastic Modulus: At low temperatures, the Poisson's ratio of a magnetically transformed austenitic stainless steel produces a corresponding extreme value.
