Ductile Cast Iron_Baidu Encyclopedia_Spheroidal Ductile Iron Pipe Manufacturer Ductile iron is obtained by spheroidizing and inoculating spheroidal graphite, which effectively improves the mechanical properties of cast iron, in particular, improves the plasticity and toughness, and thus obtains higher strength than carbon steel. Ductile cast iron is a kind of high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. Based on its excellent performance, it has been successfully used to cast some mechanical complexes with strength, toughness and wear resistance. Highly demanding parts. Ductile iron has rapidly developed into a widely used cast iron material that is second only to gray cast iron. The so-called "iron-based steel" mainly refers to ductile iron.
