Ductile iron

The chemical composition of ductile iron in addition to iron is usually: carbon content of 3.0~4.0, silicon content of 1.8~3.2, manganese, phosphorus, sulfur content of not more than 3.0 and the right amount of rare earth, magnesium and other spheroidizing elements.

  • Description
  • Hebei Shengli Casting Industry Co., Ltd. provides various types of ductile iron castings and gray iron castings. The industry involves auto parts, agricultural machinery parts, construction machinery parts, train and railway parts, cast iron parts for agricultural water conservancy and electric power, etc. Shengli Casting Industry has the production and rough processing capabilities of cast iron parts, advanced production equipment, complete testing equipment, and supports cooperation methods such as drawing customization, sample customization, OEM, etc.

    Ductile iron is a kind of high-strength cast iron material developed in the 1950 s. Its comprehensive performance is close to that of steel. Based on its excellent performance, it has been successfully used in casting some parts with complex force, strength, toughness and wear resistance. Ductile iron has rapidly developed into a cast iron material that is second only to gray iron and is widely used. The so-called "iron on behalf of steel", mainly refers to the ductile iron.

    Ductile iron is spheroidal graphite obtained by spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, so as to obtain higher strength than carbon steel.

    According to modern archaeological research, a large number of cast iron-related relics and relics have been found at the back end bay cast iron site in Xinzheng Zheng Han's old city. The back end bay cast iron site is located in the southwest of Dongcheng District in Xinzheng Zheng Han's old city, covering an area of nearly 100000 square meters. The site is an official handicraft workshop for casting tools and farm tools in the capital of South Korea in the middle and late Warring States period. Decarbonization kiln was first discovered at the cast iron site in Tuiouwan, Henan Province, advancing the history of ductile iron in China by at least 200 years. It is at least 2000 years earlier than the West.

    The chemical composition of ductile iron in addition to iron is usually: carbon content of 3.0~4.0, silicon content of 1.8~3.2, manganese, phosphorus, sulfur content of not more than 3.0 and the right amount of rare earth, magnesium and other spheroidizing elements.

    Ductile iron has been used in almost all major industrial sectors, which require high strength, plasticity, toughness, wear resistance, resistance to severe thermal and mechanical impact, high or low temperature resistance, corrosion resistance and dimensional stability. In order to meet these variations in use conditions, ductile iron has many grades that offer a wide range of mechanical and physical properties.
