Ductile iron is a high-strength cast iron material developed in the 1950s, its comprehensive performance is close to that of steel, and it is based on its excellent performance that it has been successfully used to cast some complex force, strength .Toughness.It has been successfully used to cast parts with complex forces, high strength, toughness and wear resistance.

Ductile Iron Properties

Characteristic 1: Ductile iron has very good impact resistance and ductility.This is because the graphite flakes inside the ductile iron will be turned into very fine carbon elements through a special treatment, and these fine carbon elements will enter into the gaps of the iron elements, which will greatly strengthen the physical properties of the ductile iron and thus have very good impact resistance.We also know that graphite is not ductile, but iron has good ductility, and the two together perfectly inherit the advantages of each, making ductile iron both impact resistance and ductility.Characteristic 2: Ductile iron can effectively prevent cracks.In the industry, we call it the crack terminator. Through the microscope, experts can clearly see that the cracks produced by iron stop when they crack into the graphite spheres.This is because the graphite ball has a very high stability, the probability of cracking is very small.Characteristic 3: Corrosion resistance.As we said above, ductile iron is graphite element into the gap of iron element.In this way, corrosive objects cannot corrode the iron elements.

Ductile Iron Price

The price of ductile iron is usually 1750 yuan per ton, and the price of ductile iron from manufacturers in each area is different, like Liaocheng City Development Zone Tongjia Pipe Industry Co., Ltd. ductile iron pipe is 2650 yuan, Ningxia Share Business Co., Ltd. low phosphorus and low sulfur ductile iron Q12 is 2100 yuan, Shandong Province Baijia Pipe Industry Co.

Ductile iron uses

Pressure pipeline and fittings: many big industrial countries use ductile iron as the material for making pipeline and fittings, because it can be more resistant to pressure during transportation than ordinary cast iron pipeline, and it is also more convenient and faster during construction, so it is wise to choose it as the material for pressure pipeline.Automotive application: ductile iron is mainly used in the automotive industry for the generator part, gears.Bushing part and brake and special device part.Just like the famous Ford, almost all the crankshaft parts are made of ductile iron.Agricultural machinery and construction applications: agricultural machinery in general needs to last for a long time and ductile iron forms the components to achieve this.In addition, some bulldozers used in construction or road paving.Ductile iron is also used in cranes etc.
