" Cast iron is brittle Fonderie Saguenay are a jobbing shop specializing in producing components in materials such as gray iron and ductile iron. The following table has been compiled to assist with the selection of the ideal grade of cast iron for your castings. The paper discusses the reasons for the current trend of substituting ductile iron castings by aluminum alloys castings.In addition it has been shown that thin wall wheel rim made of ductile iron can have the same weight, and better mechanical properties, than their substitutes made of Ductile iron castings are spherical graphite through spheroidizing treatment, which are of relatively high mechanical properties, plasticity and toughness, therefore ductile iron is better than carbon steel in strength. Ductile Iron is not a single material, but a family of materials offering a wide range of properties obtained through microstructure control.The ASTM has five standards covering Ductile Iron castings. The amount of steel scrap in the charge must be that The study was designed to investigate the effects of the charge, melting conditions, nodularizing and inoculation on the ductile iron castings properties. However, if the yield stress/cost ratio of the various materials is considered as- cast Ductile Iron is most of the time the winner (1)! The analytical approach taken by Stefanescu (2), who included in the material evaluation mechanical properties, density and cost Ductile irons possess reasonably high strength, good ductility and resistance to shock and also have some attractive properties, such as castability, machinability, wear resistance and impact resistance, as compared to those of steels. A reduction in the thickness of castings leads to an increase in Ductile iron or popularly known as Spherodized graphite iron (SG iron) is a special variety of cast iron having carbon content more than 3 and has graphite present in compact, spherical shapes.This unique property enables ductile irons to be used for numerous industrial applications. Ductile iron is a family of cast graphitic irons which possess high strength, ductility and resistance to shock.
The improved mechanical properties increase its resistance to breakage from physical load, or mechanical and thermal shock far above that of gray iron. In many cases, the composition of an ADI casting differs little from that of a conventional ductile iron casting, the alteration in properties being achieved by the addition of alloys like nickel, copper and molybdenum at quite low levels followed by the austempering heat treatment. Malleability and ductility of cast iron are fre-quently emphasized. So far, ductile iron has only been surpassed by cast steel and occasionally by malleable cast iron. It must be admitted that these properties are only rarely required or used. Properties: Five grades of ductile iron are classified by their tensile properties in ASTM Standard A536. SAE Standard J434c (for automotive castings and similar applications) identifies these five grades of ductile iron only by Brinell hardness. 3.1 высокопрочный чугун с шаровидным графитом (ductile iron): Тип чугуна, в котором графит присутствует преимущественно в шаровидной форме.16 centrifugal-cast ductile iron pipes.This method takes advantage of the properties of foam to simply and cheaply form castings that The Ductile cast iron contains graphite it is in the form of discrete nodules or spheroids. This paper deals with some factors influencing microstructure and mechanical properties of ductile cast iron (DCI). Good casting properties of ductile iron castings allow them parts of complex shape, eg, reinforcement parts (valves, troynikov and others.), cars, agricultural and other machines. — Ductile iron pipe, Centrifugal casting, Analysis of Parameters, optimization of parameters like temperature and flowIn static calculations, pipes in ductile iron are therefore considered as having piable properties or being flexible pipes. composition of iron on known data of express-analysis and for optimization technical process of obtaining castings of ductile iron at Public corporation «Gomel foundry «TSENTROLIT». The obtained dependences allow: to predict obtaining of metal structures and technological properties of cast The Different grades of Ductile Iron Castings are produced by obtaining different matrix microstructures in the Iron. Alloying elements may be added to enhance as cast properties of Ductile Iron. Cast iron is generally thought of as a weak, dirty, cheap, brittle material that does not have a place in applications requiring high strength and defined engineering properties. While gray cast iron is relatively brittle by comparison with steel, ductile iron is not.

An as-cast Ductile Iron casting is normalized in order to: break down carbides, increase hardness and strength, and produce more uniform properties (see Figures 3.16 and 3.18). Ductile Iron - Ductile iron casting, produces strong ferrous metal parts which display the ability to withstand impacts well without rupturing easily.The addition of Magnesium affects the properties displayed by ductile iron. Ductile cast iron (also known as nodular graphite iron, spheroidal graphite iron, and SG iron) bridges the gap between gray iron and steel.Ductile iron has mechanical properties approaching steel. Its tensile strength ranges from about 340 MPa to 1030 MPa as cast. 3. Ductile iron castings outperform cast steels and gray iron in many applications: The improved mechanical properties of ductile iron increase its resistance to breakage from physical load, or mechanical and thermal shock far above that of gray iron. The ductile iron whose properties reached the grade of QT600-3 was produced by Zhu Xianyong  using combination 0.6 Cu with 0.4 Mn.permanent moulds on mechanical properties of gray and ductile iron. Modern Cast Iron, 2005, 5: 1921. (in Chinese). Compared to other kinds of cast iron, specifically grey iron, ductile iron castings are much less brittle and are more resistant to impact and fracturing.Many different elements can be added to the iron composition to enhance or alter its properties. The castings of ductile iron will be ferritic as-cast only when large amount of pig iron in the charge and in addition some-steps inoculating treatment are used.
