Ductile iron is one of most applicable material in automotive industry. This metal is usually used for manufacturing the crankshafts and axles. Inoculation step of these parts is very important and sensitive, also is effective on microstructure and mechanical properties. In present work, the effect of silicon carbide (SiC) as an inoculant on the structure and properties of the suspension arm of Peugeout 405 automobile was evaluated. The aim of this research was the obtaining a method to use SiC and optimization the amount of SiC. In order to obtain this target, the percentage of ferrite and pearlite and the count and nodularity of graphite were examined. Furthermore some mechanical properties such as tensile strength and hardness were tested. The results showed that SiC is an appropriate replacement for conventional inolculant (FeSi) because SiC has a lower cost in comparing to FeSi while the properties are same.
