Although tensile data indicate that Ductile Iron has strength and ductility similar to cast steels,standard notched Charpy tests suggest that Ductile Iron has significantly lower fracture toughness,with energy values in the range 16-24 joules (12-18 ft lbf) compared to cast steels with 60-75 joules (44-55 ft lbf).Ductile Iron Data - Section 2Unlike Gray and Ductile Iron,Malleable Iron is cast as a carbidic or white iron and an annealing or malleablizing heat treatment is required to convert the carbide into graphite.The microstructure of Malleable Iron consists of irregularly shaped nodules of graphite called temper carbon in a matrix of ferrite and/or pearlite.Ductile Iron - Metal TechnologiesDuctile Iron Production Capabilities.Metal Technologies currently has the capacity to produce 110,000 tons of ductile iron each year.Our casting sizes range from 1 lb.to 40 lbs.We produce all standard grades of ductile iron including 65-45-12,80-55-06,and 100-70-03 as well as austempered ductile iron,and customer specific grades.Ductile
Ductile iron,also known as nodular or spheroidal graphite cast iron,is a type of cast iron known for its impact and fatigue resistance,elongation,strength,and wear resistance due to the round graphite structures in the material.The graphite structure of ductile iron is the primary reason for the higher strength and ductility,which makes Different Types Of Cast Iron White cast iron,Grey cast The resultant cast iron has properties that vary from both grey and white cast iron.In case of malleable cast iron,the graphite structure is formed into irregularly shaped spheroidal particles rather than flakes that are usually present in gray cast iron.This make the malleable cast ironDifference Between Ductile Iron and Cast Iron Compare Mar 05,2011 Chinese Material Grades of Gray Iron and Ductile Cast Iron#0183;The key difference between ductile iron and cast iron is that we use ductile iron for water pipes due to its durability while we use cast iron usually for engineering and construction structures because of its stability..Ductile iron and cast iron are useful in the metal industry on an everyday basis.However,the two alloys have different characteristics that result in them being
Gray iron is an ideal metal for bearings and bushings.Ductile iron is much better for moving parts,because it is more malleable and more impact resistant than gray iron.Our continuous cast ductile iron is commonly used for pistons and other machinery requiring high tensile strength.Explaining the Basics of Hydraulic and Pneumatic SystemsChinese Material Grades of Gray Iron and Ductile Cast IronThe Chinese cast iron material grades were named by HT for gray cast iron,and QT as the ductile cast iron.The followings are their detailed grades,and related physical properties.China S.G.Iron Castings - Gray Iron,Ductile Iron,Steel Material Grades Ductile Cast Iron,Nodular Cast Iron,Spheroidal Graphite Iron,Spherulitic Graphite Cast Iron,SG Iron ISO1083 400-15 400-18 450-10 500-7 600-3 700-2 ASTMA536 60-40-18 60-42-10 65-45-12 70-50-05 80-55-06 80-60-03 100-70-03 DIN1693 GGG40 GGG50 GGG60 GGG70
