Ductile Iron Pipe Suppliers

Ductile iron is a brittle material. First of all, cast iron means that the carbon content is greater than 2.1% (the carbon content of ductile iron is 3.50-3.90%, and the metallographic structure is: ferrite + pearlite), high carbon content, and hardness It must be high. Secondly, the spheroidization of the nodular ink means that the size of the metal particles becomes smaller, which will also increase the strength and hardness of the material. So in general, the hardness of ductile iron pipe for sale is very high (definitely higher than that of ordinary steel).
