The tribological behavior of stainless steel 304 and grey cast iron was investigated using the pinon-disc standard test with varying sliding speeds and normal loads. A pin-on-disc device with round tool inserts was used to conduct friction wear tests in which the linear wear of the tribo-pairs were continuously recorded versus sliding distance. For the quantitative comparison of the wear resistance of the material was tested by calculating the weight loss. Scanning electron microscopy (SEM) was

... applied for observations of wear scars and wear products, and the identification of the predominant wear mechanisms which occurred. Some specific frictional behaviors and relevant wear mechanisms observed for both steel 304 and cast iron sliding were highlighted and quantified. It was concluded that with the increase in sliding speed and normal load wear behavior shown by stainless steel 304 was more as it become soften with the increase in the load. But the wear behavior shown by grey cast was low due to the presence of graphite.
