Galvanized flat washers are made of steel as the base material, after electroplating or hot dip galvanized treatment, and have the advantages of corrosion resistance and not being easy to deform. In addition, galvanized flat gaskets are relatively low in price, easy to process and produce, and are often used in construction materials, auto parts, and other fields. The suitable working temperature of the carbon steel gasket should not exceed 538 ° C, especially in the oxidizing medium, the temperature should not be too high. When manufacturing inorganic acid, neutral, or acidic salt solution equipment, if carbon steel gaskets are used, the equipment is prone to failure under hot water conditions; However, carbon steel washers can be used for manufacturing equipment with high concentrations of acid and alkali solutions. 20 alloy is a kind of alloy steel, its sulfuric acid corrosion resistance is superior, its elements are mainly iron, and nickel, generally composed of 45% iron (Fe), 24% nickel (Ni), 20% chromium (Cr), and a small amount of molybdenum (Mo) and copper (Cu). 20 The suitable operating temperature of the alloy washer should not exceed 815℃.
