Jiaxing bearing small make up to tell you about the physical properties of stainless steel

There is rotational, have HRB bearing ( ) On the physical properties of stainless steel, today we invite our jiaxing bearing engineer for everyone to do a detailed introduction and guidance, hope everyone can learn. Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. The physical properties of the stainless steel mainly by the following aspects: (1) thermal expansion coefficient caused by temperature change material measure changes of the elements. Is inflation - temperature curve slope expansion coefficient, instantaneous expansion coefficient is a particular temperature slope, average slope between the two specified temperature is the average thermal expansion coefficient. Expansion coefficient can be expressed in volume or length, usually expressed in length. (2) the density of the material density is the quality of the material per unit volume, unit is kg/m3 / in3 or 1 b. (3) elastic modulus when the force f in the ends of the unit length arrises live objects can cause changes in the unit of length, the force per unit area known as the modulus of elasticity. Unit 1 b/in3 or N/m3. (4) resistivity in unit length measure the resistance between two opposite of cube material, unit with & Omega; 吗? μm; Ω 吗? Cm or ( Have waste) Ω / ( circularmil。 英国《金融时报》) To represent. (5) magnetic permeability dimensionless coefficient, said the material is easy to be magnetized degree, is the ratio of the magnetic induction intensity and magnetic field strength. 6. Melting temperature range determined to start finished coagulation, and the temperature of the alloy. All landowners heat unit mass of material temperature changes needed to 1 degree of heat. Both in English and CGs system heat value is the same, because the unit of heat ( Bju international or CAL) Depends on the unit mass of water by 1 degree of calories. Specific heat values in international system of units and inch or CGS system is different, because the unit of energy ( J） Are set according to the different definitions. Specific heat of the unit is the Btu ( 1 b吗? 0F) And J/( 公斤吗? k） 。 Was a measure of the thermal conductivity material thermal conductivity rate. In the unit cross-sectional area of material based on unit length of 1 degree temperature gradient, the thermal conductivity is defined as the unit of time the heat conduction, thermal conductivity unit for the Btu/( h ? 英国《金融时报》吗? 0F) Or w/( m ? K) 。 Pet-name ruby thermal diffusivity is to determine the internal temperature of the material removed rate before a performance, is the product of thermal conductivity compared to heat and density ratio, thermal diffusivity unit in Btu/( h ? 英国《金融时报》吗? 0F) Or w/( m ? k) Said.
