WebBainitic Heat Treatment of Pearlitic Malleable Iron. Both upper and lower bainite can be formed in pearlitic malleable iron with a marked increase in tensile strength and hardness but with a decrease in ductility. A pearlitic malleable iron (2.6C-1.4Si-0.5Mn-0.1S), annealed at 930°C (1700°F) for 16 h, air quenched and tempered at 680°C (1250 ... WebMalleable iron is a type of cast iron that has most of its carbon in the form of irregularly shaped graphite nodules.

WebPearlitic malleable irons would be stronger but less ductile than ferritic malleable cast irons for the same reasons as for ductile iron. Fracture toughness values in the range 60–70 MPa m 1/2 have been reported ( Bradley and Srinivasan 1990) for ferritic grades, values somewhat less than for a similar ferritic ductile iron. WebStandard or ferritic malleable iron is satisfactory for use as a cast, soft magnetic material. It is made by heat-treating white iron. In addition to its magnetic properties, it can be readily cast into intricate shapes and is one of the most machinable ferrous metals. By merely changing the heat-treatment, pearlitic or martensitic malleable iron can be produced from …

WebPearlitic malleable irons These have a pearlitic rather than ferritic matrix which gives them higher strength but lower ductility than ferritic, blackheart irons.
