Electric high-temperature ventilation butterfly valve with heat dissipation

Electric high-temperature ventilation butterfly valve with heat dissipationIntroduction;

310S stainless steel is an austenitic chromium nickel stainless steel, equivalent to China's 0Cr25Ni20, with excellent oxidation resistance and corrosion resistance. Due to the higher percentage of chromium and nickel, it has much better creep strength and can continue to operate at high temperatures, with good high temperature resistance. When the temperature exceeds 800, it begins to soften and the allowable stress begins to continuously decrease, with a high operating temperature of 1200 ℃. Due to the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. High temperature resistant steel pipes are specially used for manufacturing electric furnace tubes and other applications. After increasing the carbon content in austenitic stainless steel, its strength is improved due to its solid solution strengthening effect. The chemical composition characteristics of austenitic stainless steel are based on chromium and nickel, with the addition of elements such as molybdenum, tungsten, niobium, and titanium. Due to its face centered cubic structure, it has high strength and creep strength at high temperatures.
