Detailed Product Description: | 316 Air Force 201 stainless steel bar square bar hexagonal bar steel - Shenzhen Air Force to provide the physical properties of stainless steel: Carbon, nitrogen, high-manganese austenitic stainless steel, such as 1Cr17Mn6NiSN, 1Cr18Mn8Ni5N series and high-manganese austenitic stainless steel, etc., in a large amount of processing conditions, pressure ε phase transformation will occur, so keep non-magnetic. Temperatures above the Curie point, even if the magnetic material will lose magnetism. However, some austenitic stainless steel such as 1Cr17Ni7, 0Cr18Ni9, because their organization is metastable austenite, thus making a large amount of cold working pressure or low temperature processing will occur when the martensitic transformation itself will have magnetic permeability and rate will also increase. (1) modulus of elasticity Ferritic stainless steel at room temperature the longitudinal elastic modulus of 200kN/mm2, austenitic stainless steel of the longitudinal elastic modulus of 193 kN/mm2, slightly lower than the carbon steel. As the temperature decreases the longitudinal elastic modulus, Poisson's ratio increases, transverse elastic modulus (stiffness) was significantly decreased. Longitudinal elastic modulus of hardening will affect the collection and organization. (2) The density of chromium-containing ferritic stainless steel with high density, high nickel content and high manganese content austenitic stainless steel of the density, character spacing at high temperatures because of the increased density of smaller. Third, the physical properties of low temperature (1) thermal conductivity Various types of stainless steel in the low temperature thermal conductivity of slightly different size, but in general the thermal conductivity at room temperature 1 / 50. At low temperatures with the magnetic flux (flux density) increases the thermal conductivity increases. (2) heat capacity At very low temperature, specific heat capacity of stainless steel there are some differences. Temperature specific heat suffers a great impact, when in the heat capacity 4k can be reduced to room temperature heat capacity of 1 / 100. (3) Thermal Expansion For austenitic stainless steel, the following shrinkage in 80k (as opposed to 273K) of slightly different size. Nickel content on the shrinkage to a certain extent. (4) resistivity All grades at very low temperatures the size of the difference between the resistivity increase. Alloying elements on the resistivity of size greater impact. (5) magnetic At low temperatures, austenitic stainless steel with the quality of materials of different magnetic susceptibility effect of the load differences. Different alloying elements are also differences. Different grades of permeability no difference. (6) The modulus of elasticity At low temperatures, the changing magnetic austenitic stainless steel to produce the corresponding Poisson's ratio of its extreme value. |
