General Physical Properties

As with other materials, the main physical properties include the following 3 aspects: Melting point, heat, thermal conductivity and linear expansion coefficient, such as thermodynamic properties, resistivity, conductivity and permeability, such as electromagnetic properties, as well as Young's elastic modulus, stiffness coefficient and other mechanical properties. These properties are generally considered to be intrinsic properties of the stainless steel material, but are also affected by the temperature, the degree of processing and the intensity of the magnetic field. In general, stainless steel and pure iron compared with low thermal conductivity, large resistance, and the line expansion coefficient and permeability and other properties according to the crystalline structure of stainless steel itself.

Correlation between Physical Properties and Temperature

Specific Heat Capacity

With the change of the specific heat capacity of the temperature change, but in the process of temperature changes in the metal tissue in the event of phase change or precipitation, then a significant change in capacity.

Coefficient of Thermal Conductivity

Under 600 ℃, the thermal conductivity of various stainless steels is basically within the range of 10~30W/(m·℃), and the thermal conductivity increases with the temperature. At 100 ℃, the stainless steel thermal conductivity is from large to small order of 1Cr17,00Cr12,2 Cr 25N,0 Cr 18Ni11Ti,0 Cr 18 Ni 9,0 Cr 17 Ni 12Mο2,2 Cr 25Ni20. The thermal conductivity of 500 ℃ is 1 Cr 13,1 Cr 17,2 Cr 25N,0 Cr 17Ni12Mο2,0 Cr 18Ni9Ti and 2 Cr 25Ni20 in order of large to small. Austenitic stainless steel thermal conductivity is slightly lower than other stainless steel, compared with ordinary carbon steel, 100 ℃ austenitic stainless steel thermal conductivity of about 1/4.

Coefficient of Linear Expansion

In the range of 100-900 ℃, the line expansion coefficients of the main grades of stainless steels are basically 10ˉ6~130*10ˉ6℃ˉ1, and the increasing trend is with the increase of temperature. For the precipitation hardening stainless steel, the linear expansion coefficient of the size of aging treatment temperature to determine.


In 0~900℃, all kinds of stainless steel major grades of resistance to the size of the basic 70*10ˉ6~130*10ˉ6Ω·m, and with the increase in temperature has a tendency to increase. When used as a heating material, the material with low resistivity should be chosen.


Austenitic stainless Steel has a very small permeability, so it is also called nonmagnetic. The steel with stable austenitic body structure, such as 0 Cr ni 10, 0 Cr ni 20, and so on, even if the large deformation of more than 80% is processed, it will not be magnetic. In addition high

Physical Properties of Stainless Steel

Carbon, high nitrogen, high manganese austenitic stainless steel, such as 1CR17MN6NISN, 1CR18MN8NI5N series and high manganese austenitic stainless steel, etc., in the large pressure under the processing conditions will occur ε phase transition, so remain non-magnetic. Even the strong magnetic material loses its magnetism at the high temperatures above the Curie point. But some austenitic stainless steel such as 1cr17ni7, 0Cr18Ni9, because of its organization for the sub-stable austenite organization, so in the process of large-scale cold processing or low-temperature processing will occur martensite phase change, itself will have magnetic and permeability will be increased.

Elastic Modulus

The longitudinal elastic modulus of ferritic stainless steel at room temperature is 200kn/mm2, and the longitudinal elastic modulus of austenitic stainless steel is 193 kN/mm2, which is slightly lower than that of carbon structural steel. As the temperature increases, the longitudinal elastic modulus decreases, the Poisson ratio increases, and the transverse elastic modulus (stiffness) decreases significantly. The longitudinal elastic modulus will have an effect on the processing hardening and the organization set.


Ferritic stainless steel with high chromium content is small in density, with high nickel content and high manganese content of austenitic stainless steel density, at high temperature due to the increase in the density of character spacing smaller.
