IS 8329 (2000): Centrifugally Cast (Spun) Ductile Iron ...

nodular or spheroidal form in the resultant casting. It differs from cast iron by greater tensile strength and its significant elongation at break. Ductile iron offers: a) high resistance against breakage due to impact; b) high tensile strength, comparable to that of mild steel so that the pipes can be used for higher working ...

DUCTILE IRON PIPE - McWane

Due to its spheroidal graphite form, Ductile Iron has approximately twice the strength of Gray Iron as determined by tensile, beam, ring bending, and bursting tests. Its impact strength and elongation are many times greater than Gray Iron’s. As these photomicrographs show,Ductile Iron (above left) differs from Gray Iron (above right) in that

Sedimentary Rocks and the Rock Cycle

Classifications are describe as deviations from rounded or spheroidal grain shapes. Well rounded grains are smooth with rounded edges.. Moderately rounded grains are in-between the sharp, angular edges of a poorly rounded grain and the smooth, roundness of a well-rounded grain. Poorly rounded grains may be sharp or angular. 11 Table of Contents

Metallography and Microstructures of Cast Iron

microstructure of spheroidal graphite in ductile iron close to the edge of the specimens, which were cut off from a 30 mm (1.2 in.) diameter bar and polished with and without embedding in a polymer resin, respectively. In the specimen pre-pared without embedding in a resin, the graphite was pulled out, while in the specimen that was
