Ductile iron is a new sand foundry process and the difference from ordinary ones is generally in terms of texture. It is generally used to produce manhole covers and pipe fittings. Density: similar to the density of steel. What is gray iron? Gray iron casting is a kind of cast iron and the internal carbon exists as flake graphite. The fracture is gray so it is referred to as gray iron.

Ductile iron is a newer alloy than gray iron. While cast iron has been around as far back as 5th century B.C. ductile iron was first created in 1943. Ductile iron is more elastic than gray iron. It has twice the tensile strength of cast iron and a yield strength of 40k while cast iron has no yield strength at all.
Read MoreDuctile iron offers numerous machining advantages over gray iron. Ductile continuous cast iron has made its name in the machining industry from its high tensile strength and flexibility. Its ductility makes it great for being shaped into wires and other applications that require a certain level of elasticity.

Ductile iron vs. gray iron. Some iron casting buyers may be confused about the ductile iron and gray iron so herein we discussing the ductile iron versus gray iron. The graphite in gray iron is flaky shape but the graphite in ductile iron is spherical shape. Therefore gray iron has lower strength and easy fragile compared with ductile iron.
Read MoreDuctile iron also known as ductile cast iron nodular cast iron spheroidal graphite iron spheroidal graphite cast iron. While most varieties of cast iron are brittle ductile iron has much more impact and fatigue resistance due to its nodular graphite inclusions that are spherical in shape rather than striated.

Grey Iron Castings amp; Grey Cast Iron Principles. The term grey is used because of the colour of the fracture surface if a piece is broken. If molten cast iron is allowed to cool normally the carbon comes out of solution and forms flakes of graphite which run through the ferritepearlite matrix hence the alternative term flake graphite iron.

In gray cast iron flakes of graphite are embedded through the surface and are visible in highly-polished gray iron. Ductile cast iron has 3.2â€3.6 carbon 2.2â€2.8 silicon and some small percentage of a “nodulizing element.†Discovered in 1943 ductile had many of the same properties as malleable iron only it had these properties right out of the mold.
