Austenitic stainless steel compared to carbon steel, having the following characteristics: 1) high electrical female rate, Linyi captive screws, about five times the carbon steel. 2) a large linear expansion coefficient, 40% larger than carbon steel, and as the temperature rises, captive screws, stainless steel screw linear expansion coefficient values ??are correspondingly increased. 3) low thermal conductivity, Zibo captive screws, about 1/3 of steel. Material Category austenitic stainless steel: austenitic stainless steel is the most basic alloying elements chromium and nickel grades are typically about 18 percent chromium, nickel about 8% of the Cr-Ni austenitic stainless steel, often called as 18-8 stainless steel.
