Why is cast iron better than steel?
Alloy cast iron is a kind of cast iron, with some alloy elements (such as silicon, manganese, phosphorus, nickel, chromium, molybdenum, copper, aluminium, boron, vanadium, tin, etc.) obtained. Alloying elements change the matrix structure of cast iron, and accordingly have the characteristics of heat resistance, wear resistance, corrosion resistance, low temperature resistance, or non-magnetic.
High strength ductile iron has excellent corrosion resistance, and mechanical properties of very high (quite general steel), especially showed strong resistance to corrosion in the corrosive environment, the concave spot corrosion rate in the ocean is only 001~0125mm/a.
Cast iron is divided into:Grey cast iron. White cast iron. Malleable cast iron. Nodular cast iron. Vermicular graphite cast iron. The alloy cast iron.
