white iron casting

Composition of White Cast Iron. With a lower silicon content (containing less than 1.0 wt% Si – graphitizing agent) and faster cooling rate, the carbon in white cast iron precipitates out of the

White cast iron displays white fractured surfaces due to the presence of an iron carbide precipitate called cementite.

14/05/  · Cast iron is an important engineering material with a number of advantages, mainly good castability and machinability and moderate mechanical properties. White cast iron contains 1.8 % -3.6 % C, 0.5 % -1.9 % Si and 1 % – 2 % manganese (Mn). White cast irons are so called because when broken, the fracture surface is white.

Malleable Iron Casting. Malleable cast iron begins as a white iron casting, then heat treated at temperatures of about 950°C for two or a single day, and then it is cooled for the same period of time. The carbon in iron carbide then transforms into graphite and ferrite plus carbon due to this heating and cooling process. This is a low process

07/07/  · Iron casting is a known procedure being done in manufacturing. This process involves melting material and poured into a mold. The hollow cavity in the mold helps achieve

White cast irons are usually made by limiting the silicon content to a maximum of 1.3 percent, so that no graphite is present and all of the carbon exists as 

White cast iron is bright white or dark white in cross-section, with coarse grains and obvious directionality, where all the carbon elements are present in the form of carburized body (Fe3C). Characteristics The carbon content of white cast iron is about 2.5% and the content of silicon is less than 1%.
