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

When white iron is sheared, the fractured face appears white due to the absence of graphite. The cementite microcrystalline structure is hard and brittle with a high compressive strength and good wear resistance. In certain specialized applications, it is desirable to have white iron on the surface of the product.

Melting point of martensitic white cast iron (ASTM A532 Class 1 Type A) steel is around 1260°C. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition in which the solid and liquid
