The physical properties of Sch40 ASTM A53 Steel Hot Dipped Gi Pipe will change under certain conditions. Temperature is a common factor affecting its physical properties. Let's discuss the effect of temperature on its physical properties.
1. Specific heat capacity
The study found that the specific heat capacity of Sch40 ASTM A53 Steel Hot Dipped Gi Pipe is different at different temperatures. In the change of temperature, the metal structure will produce precipitation or phase transformation, so the specific heat capacity will be significantly changed.
2. Thermal conductivity
Below 600℃, the thermal conductivity of Sch40 ASTM A53 Steel Hot Dipped Gi Pipe is basically within 10~30W/(m·℃), but when the temperature exceeds 600℃, the thermal conductivity will increase. The higher the temperature, the higher the thermal conductivity. high.
3. Linear expansion coefficient
Similar to thermal conductivity, when the temperature is in the range of 100-900℃, the linear expansion coefficient of Sch40 ASTM A53 Steel Hot Dipped Gi Pipe is maintained in the range of 10ˉ6~130*10ˉ6℃ˉ1, but when the temperature exceeds 900℃, its linear expansion coefficient will also increase. For those precipitation hardening types of Sch40 ASTM A53 Steel Hot Dipped Gi Pipe, the magnitude of the coefficient of linear expansion tends to vary with aging temperature.
4. Resistivity
When the temperature is in the range of 0~900℃, the resistance of the precision stainless steel strip is basically maintained at 70*10ˉ6~130*10ˉ6Ω·m. When the temperature increases, the resistivity increases, so if you need to use Sch40 ASTM A53 Steel Hot Dipped Gi Pipe is used as a heating material. If the heating temperature exceeds 900℃, it is not recommended to use this material.
5. Magnetic permeability
The magnetic permeability of austenitic Sch40 ASTM A53 Steel Hot Dipped Gi Pipe is relatively small, but the magnetic permeability of high carbon, high manganese austenitic Sch40 ASTM A53 Steel Hot Dipped Gi Pipe will change when processed at low temperature .
It can be seen that the effect of temperature on the physical properties of Sch40 ASTM A53 Steel Hot Dipped Gi Pipe is still relatively large, but if the temperature is controlled within a suitable range, the physical properties of Sch40 ASTM A53 Steel Hot Dipped Gi Pipe can be well exerted .
