WebTycoon Piping is one of the large suppliers for high-quality K12 Ductile Iron Pipe. Ductile iron Class K12 pipes are utilized all over the globe today, as such pipe are corrosion resistant and they also provide ductility, toughness, and strength. The wall thickness of Ductile Iron Pipe Class K12 is 7mm. For both Ductile Pipe Class K9 and K12 ... WebThe term cast iron refers to iron-carbon-silicon alloys that contain 2.5-4 % carbon and usually 1-3 % silicon. In grey irons, the carbon is present as graphite; in white cast iron it is present in the form of iron carbide and alloy carbides. Cast iron has good castability and machinability, as well as moderate mechanical properties.
