The mechanical properties of ductile iron are superior to those of gray cast iron and comparable to those of steel; consequently, it can replace cast steel and forged steel in the manufacture of various components subject to heavy loads, complex stresses, and wear.
The advantages lie not only in their high strength and toughness but also in their excellent machinability and weldability. These qualities facilitate the production of complex shapes and precise dimensions, while also simplifying subsequent maintenance and replacement. Furthermore, ductile iron castings exhibit good heat and cold resistance, maintaining stable performance under extreme temperature conditions.
