Fast delivery Malleable Iron Sand Casting Company - Custom Gray Cast Iron Sand Casting – RMC Foundry Detail:
When we cast the gray iron, we strictly follow the chemical composition and mechanical properties according to the stardards or requirements from the customers. Besides, we have the ability and equipment to test if there is casting defects inside the gray iron sand castings.
The ferrous alloys which have carbon contents of more than 2% are called cast irons. Though cast irons can have a carbon percentage between 2 to 6.67, the practical limit is normally between 2 and 4%. These are important mainly because of their excellent casting qualities.
Gray iron castings are cheaper than ductile iron castings, but it has much lower tensile strength and ductility than ductile iron. Gray iron can not replace the carbon steel, while the ductile iron could replace the carbon steel in some situation due the high tensile strength, yield strength and elongation of ductile iron.
From the iron-carbon equilibrium diagram, it can be observed that cast irons have essentially cementite and ferrite. Because of the larger percentage of carbon, the amount of cementite is high resulting in very high hardness and brittleness qualities for cast iron.
