Ductile Iron Bottom Valve manufacturer tells you that as one of the best materials to replace steel, ductile iron was discovered by humans in 1949, and then quickly used by valve manufacturers. Steel with a carbon content of less than 0.3%, cast iron and ductile iron, and a carbon content of at least 3%. There is no formation of low carbon content steelmaking as the existence of free carbon graphite sheet structure. Carbon is the natural form of free graphite flakes in iron. The manufacturer of Ductile Iron Bottom Valve tells you that in ductile iron, it has been specially treated to become fine flakes of graphite balls. This allows the ball to make an improved ratio of ductile cast iron and steel to have more excellent physical properties for comparison. This is the spherical microstructure of carbon, which is more ductile and has good ductility and impact resistance, and there is no table for ductility due to the cast iron on the inner side of the sheet. The manufacturer of Ductile Iron Bottom Valve tells you that it is obtained from the ferrite matrix with the best ductility. Therefore, the load pressure of the ductile iron is in the intermediate annealing cycle of the ferrite. The spherical structure within the toughness of the cast iron can be It is easy to eliminate the phenomenon of internal cracks in the ink sheet during the manufacture of the stone valve. The manufacturer of Ductile Iron Bottom Valve tells you that in the microphotograph of ductile iron, you can see that the graphite ball terminates after the crack in the parade. In the ductile iron industry, these so-called graphite balls are "crack-stoppers" because of their ability to prevent breakage.

The manufacturer of Ductile Iron Bottom Valve tells you that compared with cast iron, ductile iron has an absolute advantage in strength. The tensile strength of ductile cast iron is 60K, while the tensile strength of cast iron is only 31K. The yield strength of ductile iron is 40K, while iron does not show the yield strength and ultimate fracture occurs. Strength spheroidal graphite cast iron-cost ratio is much better than cast iron.
Ductile Iron Bottom Valve manufacturers tell you that the strength and strength of ductile iron castings are comparable. Nodular cast iron has a higher yield strength, the lowest yield strength is 40K, and the yield strength of steel is only 36K. In most municipal applications, such as water, salt water, steam, etc., ductile iron has more corrosion and oxidation resistance than steel. Due to the microstructure of nodular cast iron, the ability to weaken vibration is stronger, and the toughness is better than steel, so it is more conducive to reducing pressure. The Ductile Iron Bottom Valve manufacturer tells you that one of the important reasons is the low selection of lower-cost ductile iron castings. The cost of ductile materials makes this more popular, the casting efficiency is higher, and the processing costs of ductile iron are less.
