Iron processing

There are two basic types of cast iron—namely white and gray White iron 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 cementite (Fe 3 C) The name white refers to the bright appearance of the fracture surfaces when a piece of the iron is broken in two Get price
