Precautions for the production of ductile iron castings
Ductile iron is a high-strength cast iron material, its comprehensive performance is close to steel. 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. It is based on its excellent performance, has been successfully used for casting some complex force, strength, toughness, wear resistance requirements of the higher parts. Ductile iron castings have 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.
