Quality control of gray cast iron

Gray cast iron is a kind of cast iron with gray cross section and carbon mainly formed by flake graphite.

The production process of gray cast iron is simple, the rate of finished product is high and the cost is low. Although it has the disadvantage of low mechanical properties, it has a series of excellent casting properties and high enough mechanical properties, and it has application properties in some aspects, such as low notch sensitivity, good damping and vibration absorption. strong wear resistance and so on. Therefore, different grades of gray cast iron have been widely used in industrial production. According to statistics, in industrial equipment. More than 80% of the parts are made of gray cast iron.
