Bazhou Kangxianzhuang Metal Stamping Parts Factory-How to choose the material of metal flat gasket accurately?

Bazhou Kangxianzhuang Metal Stamping Parts Factory-How to accurately select the material of metal flat gaskets [Hardware] For 15 years, we have been dedicated to the field of metal stamping parts with ingenuity. After more than ten years of development, we have a complete set of high-precision equipment and technical team as well as perfect scientific management in the metal stamping industry. The monthly processing capacity of more than 100 sets of molds and the production capacity of 3 million punches per day will give you answers. 1. Metal flat gasket material 1. Carbon steel: The recommended maximum working temperature does not exceed 538°C, especially when the medium is oxidizing. High-quality thin carbon steel plates are also not suitable for equipment manufacturing inorganic acids, neutral or acid salt solutions. If carbon steel is subjected to stress, the equipment accident rate under hot water conditions is very high. Carbon steel gaskets are usually used for high-concentration acids and many alkaline solutions. The Brinell hardness is about 120. 2. 304 stainless steel 18-8 (chromium 18-20%, nickel 8-10%), the recommended maximum working temperature does not exceed 760℃. In the temperature range of -196~538℃, stress corrosion and grain boundary corrosion are prone to occur. The Brinell hardness is 160. 3. The carbon content of 304L stainless steel does not exceed 0.03%. The recommended maximum operating temperature does not exceed 760°C. Corrosion resistance is similar to 304 stainless steel. The low carbon content reduces the precipitation of carbon from the crystal lattice, and the resistance to intergranular corrosion is higher than that of 304 stainless steel. The Brinell hardness is about 140. 4. 316 stainless steel 18-12 (chromium 18%, nickel 12%), about 2% molybdenum is added to 304 stainless steel. When the temperature increases, its strength and corrosion resistance will increase. When the temperature increases, it has higher creep resistance than other ordinary stainless steels. The recommended maximum operating temperature does not exceed 760°C. The Brinell hardness is about 160. 5. The recommended maximum continuous working temperature of 316L stainless steel does not exceed 760℃~815℃. The carbon content does not exceed 316 stainless steel, which has better resistance to stress and grain boundary corrosion. The Brinell hardness is about 140. 6. 20 alloy 45% iron, 24% nickel, 20% chromium and a small amount of molybdenum and copper. The recommended maximum operating temperature does not exceed 760℃~815℃. It is especially suitable for manufacturing equipment resistant to corrosion by sulfuric acid, with a Brinell hardness of about 160. 7. Aluminum aluminum (content not less than 99%). Aluminum has excellent corrosion resistance and processing properties, and is suitable for manufacturing double-clamp gaskets. The Brinell hardness is about 35. It is recommended that the maximum continuous working temperature does not exceed 426°C. 8. The composition of red copper is close to pure copper, and it contains a small amount of silver to increase its continuous working temperature. It is recommended that the maximum continuous working temperature does not exceed 260°C. The Brinell hardness is about 80. 9. Brass (66% copper, 34% zinc), has good corrosion resistance under most working conditions, but is not suitable for acetic acid, ammonia, salt and acetylene. It is recommended that the maximum continuous working temperature does not exceed 260℃.
