The resistance， coefficient of linear expansion， thermal conductivity， quality， hot melt and magnetism of stainless steel pipe will change greatly at low temperature. Resistance， linear expansion coefficient decreases at low temperature; The thermal conductivity and mass heat capacity decrease sharply at low temperature; Youngs modulus (longitudinal modulus) increases when the temperature decreases. Because the austenitic series stainless steel pipe has MS point (martensite start temperature or martensite formation temperature) at low temperature (subzreo temperature)， martensite can be formed when it is kept below MS point. The formation of martensite at low temperature makes the representative steel sus (Cr-Ni) of austenitic stainless steel non-magnetic at room temperature and magnetic at low temperature.
