摘要：
By way of alloying, a sort of low-chromium heat-resistant ductile iron material was developed. Through the observation of microstructure, testing of mechanical properties and process performance, heat-resistant test, the microstructure and properties of heat resistant ductile iron of low chromium was studied. The results show that microstructure of the developed heat-resistant ductile iron is spherical graphite distributed regularly on matrix of pearlite and a small amount of ferrite; mechanical properties, processing performance and high-temperature heat resistance of samples of different chrome composition are preferable, but 1.6% of chromium component possess the best performance.
