Malleable Cast Irons

Cast irons are iron with high levels of carbon. Heat treatments and alloying element additions produce gray cast iron, malleable iron, ductile iron, spheroidal cast iron and other grades. The mechanical properties vary significantly. Nickel-containing cast irons have improved hardness and corrosion resistance. Copper or molybdenum additions improve strength. 

What are the differences between white cast iron, gray cast iron, malleable cast iron, and wrought iron ... 

Tellurium also improves the properties of electrical steels by aiding in the magnetic anisotropy, malleable cast iron (77), and spheroidal (graphitic) cast irons (see also Metal surface TiiEATiffiNTs).

This type of cast iron is made by high-temperature heat treatment of white iron castings. The mechanical properties of malleable cast irons are given in Table 3.1 usually they are applied to the fabrication of conveyor chain links, pipe fittings and gears. 

The corrosion resistance of unalloyed and low-alloy flake, nodular, malleable and white cast iron is comparable to mild- and low-alloy steel. However, these cast irons have a major advantage over steel namely, greater cross section or wall thickness than steel. Consequently, they have a...

Figure 2-4B. Forged steel socket weld fittings, WOG (water, oil or gas service). Note the working pressures are always well above actual plant operating levels and are heavy to allow for welding. Pressure classes 3000 psi and 6000 psi, sizes % in. through 4 in. nominal. Do not weld on malleable iron or cast Iron fittings. (By permission, Ladish Co., Inc.)...

Never use malleable iron fittings or pipe unless the fluid is nonhazardous and the pressure not greater than 25 psig. Always use a pressure rating at least four times that of the maximum system pressure. t lso, never use cast iron or malleable iron fittings or valves in pressure pulsating systems or systems subject to physical shock. 

Pure iron is relatively flexible and malleable, but the carbon atoms make cast iron very hard and brittle. Cast iron is used for objects that experience little mechanical and thermal shock, such as ornamental railings, engine blocks, brake drums, and transmission housings.
