Pearlitic malleable iron
Web92 rows · Pearlitic malleable irons would be stronger but less ductile than ferritic … WebPearlitic malleable irons These have a pearlitic rather than ferritic matrix which gives them higher strength but lower ductility than ferritic, blackheart irons. Weldability This depends on microstructure and mechanical properties. For example, grey cast iron is inherently brittle and often cannot withstand stresses set up by a cooling weld.

Malleable iron is a good choice for small castings or castings with thin cross sections (less than 0.25 inch, 6.35 mm). Other nodular irons produced with graphite in the spherical shape can be difficult to produce in these applications, due to the formation of carbides from the rapid cooling. See more 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 … See more Malleable iron was used as early as the 4th century BCE, and archaeologists have found malleable iron artifacts made in China between 4th century BCE and 9th century CE.
