This paper describes the application of experimental design techniques to characterize the wear behavior of two medium carbon steels designing with suitable alloying elements, Mn, Si, Al, and Cr. Application of experimental design technique enabled us to confirm the significance of the factors affecting the wear behavior with a minimum number of experiments. Attempt was to find out the dominant parameter on the wear behaviour. The experiments of sliding wear were performed under pressure range of 0.71- 1.98 MPa and sliding velocity range of 3.43-10.43 m/s. the wear specimens were obtained through hot forging process with ~ 92% reduction on the investigated alloys at a temperature of 1100 0C followed by air cooling. Microstructural investigations on the worn surfaces were undertaken. The morphology results and the general wear formulas reveal that applied pressure was found to be the most significant parameter.
