-Materials-Performance Composition Gray cast iron can be regarded as a gray cast iron matrix of carbon steel plus flake graphite. Gray cast iron is divided into three categories according to different matrix structures: ferrite matrix gray cast iron, ferrite-pearlite matrix gray cast iron, pearlite matrix gray cast iron. Mechanical properties: The mechanical properties of gray cast iron are related to the structure of the matrix and the morphology of graphite. The flake graphite in gray cast iron severely splits the matrix and easily causes stress concentration at the sharp corners of the graphite. The tensile strength, plasticity and toughness of gray cast iron are much lower than that of steel, but the compressive strength is equivalent to that of steel. It is also a common mechanical property of cast iron parts. Worst cast iron. At the same time, the matrix structure also has a certain influence on the mechanical properties of gray cast iron. The graphite flakes of ferrite matrix gray cast iron are coarse and have the lowest strength and hardness, so they are less used. The graphite flakes of pearlite matrix gray cast iron are small and have higher strength and hardness. They are mainly used for The graphite flakes of ferrite-pearlitic matrix gray cast iron, which is the most important casting to make, are slightly larger than those of pearlitic gray cast iron, but their performance is not as good as that of pearlitic gray cast iron. Therefore, gray cast iron with pearlite matrix is more commonly used in industry. Other properties: good casting performance, good vibration damping, good wear resistance, good cutting performance, low notch sensitivity, heat treatment, gray cast iron, China, Japan, Korea, United States, United States, ductile iron, China, Japan, South Korea, United States - United States characteristics : Product specifications are complete, price is favorable, packaging is intact, quality is pure, straightness is good, and inventory is large.
