There is a need for cast irons with a combined combination of properties in modern conditions. Such properties can be provided by ductile cast iron with nodular and vermicular graphite, which is essentially a hybrid cast iron in terms of microstructure. The article found that ductile iron with nodular and vermicular graphite in terms of its mechanical properties is a rational alternative to malleable cast iron, namely the grade KCh45-6 (GOST 1215-79). Also, the ratio of nodular/vermicular graphite (70…95/5…30%) was determined, which provides the data of mechanical characteristics. Differences in pearlite/ferrite ratio and hardness for ductile iron with nodular and vermicular graphite and ductile iron are shown, providing grade KCh45-6.
Key words: malleable cast iron / ductile iron with nodular and compact graphite / hybrid cast iron / mounting bracket
