malleable cast iron
malleable cast iron
Cast iron made by prolonged annealing of white cast iron in which decarburization and/or graphitization take place to eliminate some or all of the cementite. The graphite is in the form of temper carbon. There are ferritic and perlitic malleable cast irons. Their typical composition ranges are: 2.2 to 2.9 percent carbon, 0.2 to 1.3 percent manganese, 0.9 to 1.9 percent silicon, 0.05 to 0.18 percent sulfur and 0.18 percent (maximum) phosphorus.
