Application field and representative products of ductile iron

- Nov 12, 2019-

Application: Ductile iron is often used to produce parts with high requirements, such as strength, toughness and wear resistance, such as crankshafts and camshafts for automobiles, tractors, internal combustion engines, etc., as well as medium-pressure valves for general machinery.

Representative product austenite-bainite: In the early 1970s, almost three countries in China, the United States and Finland announced the successful development of austenitic-bainitic ductile iron with high strength and high toughness. ADI), this material has a tensile strength of 1000 MPa, so it is widely used in gears and various structural parts. Compared with alloy steel, ao-bead ductile iron has significant economic and social benefits.
