Properties of Gray Cast Iron ASTM A48 Class 40 The carbon and silicon contents of gray cast irons vary between 2.5 and 4.0 wt% and 1.0 and 3.0 wt%,respectively.Gray cast iron is characterised by its graphitic microstructure,which causes fractures of the material to have a gray appearance.Gray Iron ASTM A48 - Pacific Alloy Casting Co.,Inc Specification for Gray Iron Castings ASTM A-48 Gray Iron Gray iron is an alloy of carbon,silicon and iron.The first cast iron,gray iron is the most versatile of all foundry metals.The high carbon content makes gray iron easier to melt,cast and machine than other iron alloys.Gray Iron ASTM A48 Penticton FoundryAlso called grey cast iron,gray iron is a kind of cast iron with a graphitic microstructure.It has high thermal conductivity,good machinability and excellent damping capacity.Unfortunately,because of its low ductility and tensile strength,it has very little impact and shock resistance.It does,however,have good corrosion resistance because of its silicon content,which can occupy up to 6 to 10% of the content of gray iron.
Gray Iron Castings to ASTM A48.Gray iron castings are also referred to as gray cast iron,grey iron castings,it is named after the gray color of the fracture surface.Gray iron has a low tensile strength due to the flake graphite in its microstructure,so it is used for shell components where the stiffness is more important than its tensile Gray Iron Foundy Gray Iron Casting Cast Iron Casting Gray Iron Foundry Gray Iron Casting in Knoxville,TN.Gray Iron is commonly referred to as Cast Iron.The name,Gray Iron,is derived from the characteristic gray color of the casting when fractured.Characteristic properties of Gray Iron are excellent machinability,good wear resistance,high vibration absorption,and good fluidity.Iron Classification Codes and CharacteristicsGray Iron Standard Speci cations Characteristics Applications ASTM A48 gray iron castings ASTM A74 cast iron soil pipe ttings ASTM A126 gray iron castings for valves, anges pipe ttings ASTM A159 automotive gray iron castings SAE J431 automotive gray iron castings
