Introduction of Gray Cast Iron Long-neck Valve Cap:
Gray cast iron refers to cast iron with flake graphite. Because the fracture is dark gray when broken, it is called gray cast iron. The main components are iron, carbon, silicon, manganese, sulfur, and phosphorus. It is the most widely used cast iron, and its output accounts for more than 80% of the total output of cast iron. According to the shape of graphite, gray cast iron can be divided into: ordinary gray cast iron, graphite is flake; nodular cast iron, graphite is spherical; malleable cast iron, graphite is flocculent; vermicular graphite cast iron, graphite is worm-like.
Application fields of Gray cast iron Long-neck valve cap:
Valve casting is used for mechanical parts, such as machine bed, cast iron platform plate, hydraulic piston, plastic breaking mechanism, pulley, etc.
Features of Gray cast iron Long-neck valve cap:
Although the plasticity and toughness of Gray cast iron Long-neck valve cap are very low, it still has a certain strength, and the tensile strength is also very strong, which can be compared with steel, generally 3-4 times the tensile strength , which is also necessary for gray cast iron to be used as castings such as cast iron platforms and machine bases.
Gray cast iron has flake graphite, which acts as a cut on the substrate, so gray cast iron is not cut sensitive as a structural metal material.
Valve cap has good lubricating properties, and when gray cast iron is used to make parts subject to sliding friction on electromechanical equipment, it has good anti-friction properties.
