About product and suppliers: ggg40 ggg50 products are offered for sale by suppliers on Alibaba.Ductile iron can be bent without breaking, whereas cast iron is brittle and breaks when bent.
As ductile iron can be bent, it can be made into different shapes and forms. But one cannot make out different shapes and forms using cast iron.
While ductile iron is flexible, cast iron is not. When comparing the two, cast iron corrodes more quickly than ductile iron. Ductile iron consists of iron, carbon, silicon, manganese, magnesium, phosphorous and sulphur.Armstrong RML Cannon Trunnions
Tin and copper are also sometimes found. Ductile iron also consists of nodular graphite, which gives it flexibility. Cast iron mainly consists of carbon and silicon.
With regard to practical uses, ductile iron pipes are used in sewer and water lines.
Cast Iron Bar
This is because they are much stronger than cast iron. Moreover, ductile iron is better than cast iron in difficult terrains.Ktor backend
Ductile iron is mainly used in the automobile industry such as trucks, tractors and oil pumps. Cast iron is mainly seen in the construction industry. It was Keith Millis who discovered ductile iron in Cast iron has been in use for many centuries. China is credited with the invention of cast iron in the 4th century BC. It was used first for making weapons, pots, ploughshares and pagodas.
The western people knew cast iron only in the late 14th century.

Mechanical Engineering. The Difference Between. Wiki User A butterfly valve is from a family of valves called quarter-turn valves.
The "butterfly" is a metal disc mounted on a rod. Bayard E. Bosserman has written: 'Butterfly valves' -- subject s : Water-pipes, Hydrodynamics, Butterfly valves, Valves.
Asked in Mechanical Engineering Disadvantages of butterfly valve? The use of butterfly valves for control applications is limited to the valve opening range between 30 degrees to 70 degrees.
Throttling using butterfly valves is limited to low pressure drop applications. Potential cavitation is a concern when butterfly valves are used. Also possibility of a choked flow is a concern. Asked in Mechanical Engineering Is butterfly valve suitable for flow control? For certain high volume low pressure flow applications, butterfly valves or pneumatic controlled flapper valves are more than adequate to throttle the flow. For high pressure and low flow control applications hydraulic blocks, balanced valves, needle valves and globe valves are preferred.

Difference Between Ductile Iron and Cast Iron
Gray iron and ductile iron are differentiated by the type and structure of the carbon present in them. The question, of course, is which one is right for your project? For a quick summary, scroll down to the bottom of the blog and check out our chart.
Gray iron can be cast very easily and has good machineability. It is typically used in the following non-critical applications where strength is not the main required property:. Ductile Iron, because of the increased strength and ductility is used in more engineered applications:. We have included a chart comparing the two irons across a variety of factors.
The checkmark in the appropriate column indicates the better choice between the two. Necessary cookies are absolutely essential for the website to function properly. This category only includes cookies that ensures basic functionalities and security features of the website.

Our foundry has produced this material for many years, and herein, we introduce its mechanical and chemical properties and some iron castings made by this material grade. Their main mechanical properties are as followings:. However, if your clients did not denote the specific requirements to the elongation and impact resistance, then the iron foundries should meet the lowest requirements of min.
Actually, from different standards, their suggested chemical compositions are very different, but all of them denoted that the chemical composition should just be reference, and will not be taken as quality inspection standard.The village of pieve a ripoli, municipality of firenze (fi) toscana
Of course, if you need to stipulate the chemical composition to meet the special application, then you should denote the allowable chemical element range on the drawings or in your requirements. The Application of GGG40 GGG40 is a very good material grade of ductile ironwhich has good tensile strength and yield strength, and especially very high elongation rate.
The higher grade will mean the lower elongation, so GGG40 has the highest elongation rate in all ductile iron grades. This material is suitable for many industrial and civil fields. Such as automotive castings, truck and agricultural parts, various machinery casting parts, manhole covers, even for pump and valve parts. The following casting parts were produced by Dandong Foundry in China.Pystan gpu
