The physical properties of stainless steel are mainly expressed in terms of

①Coefficient of thermal expansion

The change in the measurement element of a substance due to a change in temperature. The coefficient of expansion is the slope of the expansion-temperature curve, the instantaneous expansion coefficient is the slope at a specific temperature, and the average slope between two specified temperatures is the average coefficient of thermal expansion. The coefficient of expansion can be expressed in terms of volume or length, and is usually expressed in terms of length.

②Density

The density of a substance is the mass per unit volume of that substance in kg/m3 or 1b/in3.

③Modulus of elasticity

When a force is applied to the ends of a unit length of prismatic dwelling can cause a unit change in the length of the object, the force required per unit area is called the modulus of elasticity. The unit is 1b/in3 or N/m3.

④Resistivity

The resistance measured between the two opposite sides of a unit length of cubic material is expressed in units of Ω-m, μΩ-cm or (obsolete) Ω/(circular mil.ft).

⑤ Magnetic permeability

A dimensionless coefficient indicating the degree to which a substance is susceptible to magnetization, and is the ratio of magnetic induction strength to magnetic field strength.

⑥Melting temperature range

Determines the temperature at which an alloy begins to solidify and the temperature at which it has finished solidifying.

(7) Specific heat

The amount of heat required to change the temperature of a unit mass of a substance by 1 degree. The values of specific heat are the same in both the British system and the CGs system because the unit of heat (Biu or cal) depends on the amount of heat required to raise the temperature of a unit mass of water by 1 degree. The value of specific heat in the International System of Units is different from the Imperial or CGS system because the unit of energy (J) is defined differently. The units of specific heat are Btu (1b-0F) and J/(kg -k).

⑧ Thermal conductivity

A measure of the rate at which a substance conducts heat. When a temperature gradient of 1 degree per unit length is established on a unit cross-sectional area of material, then the thermal conductivity is defined as the heat conducted per unit time, and the units of thermal conductivity are Btu/(h-ft-0F) or w/(m -K).

⑨ Thermal diffusivity

is a property that determines the rate of temperature front migration within a substance and is the ratio of thermal conductivity to the product of specific heat and density, and the unit of thermal diffusivity is expressed as Btu/(h-ft-0F) or w/(m-k).
