Cast iron is an iron-carbon alloy with carbon content greater than 2.1%, which is obtained by melting the cast city iron in the furnace and adding iron alloy, scrap steel, and recycled iron to adjust the composition.
The chemical composition is stable up to standard (the company is equipped with pre-furnace testing equipment to test each furnace molten steel to ensure that the product is cast after reaching the standard).
Cast iron is a carbon content of more than 2.11% iron carbon alloy, by industrial pig iron, scrap steel and other steel and alloy materials through high temperature melting and casting molding to get.
In addition to Fe, also contains and other cast iron carbon in the form of graphite precipitation, precipitated graphite spherical cast iron is nodular cast iron.
