Stainless steel filter due to relatively good overall performance, where access to a wide range of applications in all walks of life, then one of the physical properties of stainless steel filters are mainly in what way a modulus of elasticity: When a force is applied to the unit length of the edge When both ends of live objects can cause changes in the length of the unit, the required force per unit area is called the elastic modulus. Unit 1b / in3 or N / m3. 2, magnetic permeability: dimensionless coefficient, indicates the degree of substance easily magnetized than the magnetic flux density and magnetic field intensity. http://www.apkefeng.com/jsnews/118.html 3, thermal expansion coefficient: due to temperature changes cause changes in the material measure elements. Expansion coefficient is expandable - temperature slope of the curve, the slope of the instantaneous coefficient of expansion is a particular temperature, the average slope between two specified temperatures is the average coefficient of thermal expansion. Expansion coefficient can be expressed by volume or length is usually expressed by the length. 4, specific heat: unit mass of material required for a temperature change of a degree of heat. Both heat than the same value in the Imperial and CGs system because of heat units (Biu or cal) depending on the unit mass of water rises one degree of heat required to listen to. International System of Units specific heat values ??and inch or CGS system is different, because the unit of energy (J) are given according to different definitions. 5, density: stainless steel filter material density is mass per unit volume of the substance, the unit is kg / m3 or 1b / in3. 6, resistivity:?? Per unit length between two opposite cube material measured resistance, units with Ω m, μΩ cm or (already waste) Ω / (circularmil.ft) to represent. 7, thermal diffusivity: a performance before the matter is to determine the internal temperature of the relocation rate is the ratio of the thermal conductivity and density of the product of specific heat, thermal diffusivity unit to ??? u / (h ft 0F??) Or w / (m? k) indicates. 8, the melting temperature range of: determining start to solidify the alloy and the solidification temperature over. 9, the thermal conductivity: a measure of the rate of heat conduction material. When the temperature gradient is established a degree per unit length per unit cross-sectional area material, then the thermal conductivity per unit time is defined as the conduction of heat, the thermal conductivity in units of Btu / (h? Ft? 0F) or w / (m ? K).
