Ductile Cast Iron – IspatGuru

May 21, 2014  Ductile iron is a family of cast graphitic irons which possess high strength, ductility and resistance to shock. Annealed cast ductile iron can be bent, twisted or deformed without fracturing. Its strength, toughness and ductility duplicate many grades of steel and far exceed those of standard gray irons.

Coining is a specialized operation that can be used to both deform a Ductile Iron casting to produce its final shape, and shear off ingates, feeder necks and parting line "flash". Due to the strength of Ductile Iron, the size of casting that can be coined and the degree of deformation produced are limited.

CORROSION CONTROL Cement-Mortar Linings for

Research conducted by the Cast Iron Pipe Research Association from 1940 to 1952 showed that a thin paint coating, applied to the freshly placed cement-mortar lining, would greatly minimize moisture loss during hydration, thereby resulting in controlled cure of the mortar. Thus, this method There are two methods of cement lining Ductile Iron Pipe.
