Malleable iron information


Polycrystalline structure of malleable iron, in thin section magnified 100×

Malleable iron is cast as white iron, the structure being a metastable carbide in a pearlitic matrix. Through an annealing heat treatment, the brittle structure as first cast is transformed into the malleable form. Carbon agglomerates into small roughly spherical aggregates of graphite, leaving a matrix of ferrite or pearlite according to the exact heat treatment used.

Three basic types of malleable iron are recognized within the casting industry: blackheart, whiteheart, and pearlitic.[1]
