Stainless steel Supply correlation 303 acid resistant material wholesale physical properties and temperature (1) the specific heat capacity with temperature changes vary the heat capacity will be, but the phase transformation or precipitation changes in temperature in the process of the metal structure in the event, then the specific heat capacity will occur significantly significant changes. (2) the thermal conductivity below 600 ℃, the thermal conductivity of stainless steel is substantially within 10 ~ 30W / (m · ℃) range, as the temperature of the thermal conductivity increased with increasing trend. At 100 ℃, the thermal conductivity of stainless steel from large to small order 1Cr17,00Cr12,2 Cr 25N, 0 Cr 18Ni11Ti, 0 Cr 18 Ni 9,0 Cr 17 Ni 12Mο2,2 Cr 25Ni20.500 ℃ when the thermal conductivity by a large to a small order of 1 Cr 13,1 Cr 17,2 Cr 25N, 0 Cr 17Ni12Mο2,0 Cr 18Ni9Ti and 2 Cr 25Ni20. Thermal conductivity of austenitic stainless steel is slightly lower than the other, compared with ordinary carbon steel, 100 ℃, the thermal conductivity of austenitic stainless steel is about its quarter. (3) linear expansion coefficient in the range of 100-900 ℃, linear expansion coefficient of various types of stainless steel grades of the basic 10ˉ6 ~ 130 * 10ˉ6 ℃ ˉ1, and with increasing temperature showed an increasing trend. For the precipitation hardening stainless steel, the size of the linear expansion coefficient to determine the aging treatment temperature. (4) resistivity 0 ~ 900 ℃, all kinds of stainless steel grades than the resistance of the size of the basic 70 * 10ˉ6 ~ 130 * 10ˉ6Ω · m, and with the increase of temperature tends to increase. Stainless steel with domestic (import) stainless steel band: stainless steel coil, stainless steel springs, stainless steel stamping, stainless steel precision, stainless steel mirror, stainless steel cold-rolled, hot-rolled stainless steel, etched stainless steel, stainless steel stretch band, stainless steel polished, stainless steel flexible, stainless steel hardware, stainless steel medium hard, stainless steel high temperature zone. 2 classification cold rolled strip ① to "stainless steel / sheet" for the raw material, at room temperature by cold rolling mill rolling timber. Conventional thickness, width; ② ["cold-rolled strip / coil"] has a smooth surface, high flatness, dimensional accuracy and good mechanical properties, etc., products are mostly in rolls, can be processed into coated steel; ③ cold-rolled stainless steel strip / roll production process: ⒈ pickling → ⒉ normal lubrication of rolling → ⒊ process → ⒋ annealing → ⒌ flat → ⒍ fine cut → ⒎ packaging → ⒏ reach customers. Hot-rolled hot rolled mechanism ① thickness 1.80mm-6.00mm, width 50mm-1200mm strip. ② [hot rolled strip / sheet] with low hardness, easily processed, and good ductility. ③ hot-rolled stainless steel strip / coil production process: ⒈ pickling → ⒉ high temperature lubrication of rolling → ⒊ process → ⒋ annealing → ⒌ flat → ⒍ fine cut → ⒎ packaging → ⒏ reach customers. ① difference between hot and cold rolled steel strength, yield ratio, good hot-rolled steel ductility, toughness. ② thickness of thin cold-rolled strip, hot rolled greater thickness. ③ cold-rolled strip surface quality, appearance, dimensional accuracy is superior to the hot-rolled sheet.
