Wholesale sale of imported 410 stainless steel rod imports of grain oriented silicon steel strip material, also known as cold-rolled silicon steel strip telecommunications industry, is used to manufacture a variety of operating frequencies above 400Hz power supply transformers, pulse transformers, magnetic amplifiers, converters and other core The grain-oriented structure having a thickness not greater than 0.20mm silicon steel strip. Structural steel Delivery status: to heat treatment (annealing, normalizing, normalizing and tempering, tempering) the state of delivery. Strip under the conditions of the performance meets required standards, do not by heat treatment delivery. Ordinary steel strip allows the drawing stage without heat treatment delivery. Cold-rolled steel strip heat treatment (annealing, normalizing, normalizing and tempering) the state of delivery, should be smooth delivery. Usage: Widely used in the automotive, aviation industry and other sectors, the use of a large quantity. Cold rolled steel deep drawing cold rolled steel is used for deep drawing of complex parts drawing quality carbon structural steel, low-carbon cold-rolled steel. Delivery Status: subject to heat treatment and smooth delivery. The surface condition of the steel strip should be roughened or shiny. Usage: widely in automobiles, tractors and other industrial applications. Contain high amounts of chromium ferritic stainless steel density, large high nickel content and high manganese content of austenitic stainless steel density, character spacing at high temperatures due to increased density becomes small. Physical properties at low temperatures (1) the size of the thermal conductivity of stainless steel in low temperature thermal conductivity slightly different, but in general is about room temperature thermal conductivity of 50x. As the magnetic flux at a low temperature (flux density) is increased to increase the thermal conductivity. (2) the specific heat capacity at very low temperatures, the specific heat capacity of stainless steel there are some differences. Heat suffer greatly affect the temperature, in the 4k specific heat capacity can be reduced to below room temperature 1/100 specific heat capacity. (3) thermal expansion for austenitic stainless steel, 80k or less in shrinkage (relative to 273K) size is slightly different. Nickel content has a certain influence on shrinkage. (4) has a resistivity at low temperature differences between the various grades of resistivity to increase. Alloying elements have a greater impact on the size of the resistivity. (5) at low magnetic, austenitic stainless steel are different materials with different effects on the quality of the load magnetic susceptibility. Different alloying elements are also differences.
