Details: Cast iron: an iron-carbon alloy containing more than 2% carbon. Industrial cast iron generally has a carbon content of 2.5% to 3.5%. Carbon is mostly in the form of graphite in cast iron, and sometimes in the form of cementite. In addition to carbon, cast iron also contains 1% to 3% of silicon, as well as manganese, phosphorus, sulfur and other elements. Alloy cast iron also contains elements such as nickel, chromium, molybdenum, aluminum, copper, boron, and vanadium. Carbon and silicon are the main elements that affect the microstructure and properties of cast iron. Cast iron can be divided into:1 gray cast iron. The carbon content is high (2.7%~4.0%), the carbon is mainly in the form of flake graphite, and the fracture is gray, referred to as gray iron. Low melting point (1145~1250 °C), small shrinkage during solidification, compressive strength and hardness close to carbon steel, good shock absorption. Since the flake graphite exists, the wear resistance is good. Casting performance and cutting processing are better. It is used to manuf |
