law.resource.orgDuctile iron, also called nodular iron or spheroidal graphite iron, is characterized by the presence of graphite in 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:

www.kemostal.comCast iron is the normally casing material; alternative casing materials are spheroidal graphite iron or various grades of steel. The main casing and the inlet and outlet end covers are flanged, bolted and dowelled through flanges to ensure correct alignment. Removal of the end covers
IS 1865 (1991): Iron castings with spheroidal or nodular ...
law.resource.orgSpheroidal or nodular graphite cast iron or ductile iron is a casting alloy of iron and carbon, carbon being present in the spheroidal form. The properties of spheroidal graphite cast iron depend, particularly, on a form ( shape and size ) of the graphite and the structure of the matrix which can be chariged or altered by suitable heat ...
DUCTILE IRON PIPE - McWane
pe.mcwane.comDuctile Iron also differs from Gray Iron in that its graphite form is spheroidal, or nodular, instead of the flake form found in Gray Iron. This change in graphite form is accomplished by adding an inoculant, usually magnesium, to molten iron of appropriate composition during manufacture. Due to its spheroidal graphite form, Ductile Iron has ...
Properties and Applications of Ni-Resist and Ductile Ni ...
nickelinstitute.orgNi-Resist Austenitic Cast Iron Alloys There are two families of Ni-Resist austenitic cast irons. These are the standard or flake graphite alloys and the ductile or spheroidal graphite alloys. As time passes, the spheroidal grades, because of higher strength, ductility and elevated temperature properties, are becoming more prominent.

www.ikbooks.comStress and Strains • 7 The proof stress here is found on the basis of 0.1 per cent strain. Procedure: Draw a line parallel to the initial slope of the curve.The stress at the point where this line cuts the curve is the 0.1% proof stress.The 0.2 per cent proof stress is also found in the same
