List of malleable steel floor flange


Important detail of 1/2" npt black malleable iron thread flange

Malleable cast iron – It is cast as white cast iron, then ‘malleabilized’ (i.e., heat treated to impart ductility to the brittle material). The micro structure consists of ferrite and particles of free graphite. This cast iron encompasses a form of graphite called temper carbon. This form of graphite is produced by the heat treatment of white cast iron. When a white cast iron is heated for an extended period of time (about 60 hours) at a temperature of 960 deg C, the cementite decomposes into austenite and graphite. By slow cooling from 960 deg C, the austenite transforms into ferrite or pearlite depending on the cooling rate and the diffusion rate of carbon.

Why need carbon when produce the malleable cast iron ?

Carbon is a graphitizing element,Silicon promotes graphitization,When the content is high, it reacts,Sulfur hindered graphitization,Manganese also hindered the graphitization,so manganese also is important . Phosphorus generally has little effect,but the content is too high, will reduce the toughness of pipe fittings.
