In the present study an effort has been made to improve wear resistance of piston die through hardfacing by using different electrodes. Hardfacing is a process in which a layer of material with high mechanical strength and wear resistance is deposited on the substrate material generally by using welding process. The material deposited generally possess high hardness, which increase the wear resistance and corrosion resistance at room temperature as well as at elevated temperature. In the current investigation three different iron based electrodes E310, E316 and E410 having different chromium percentage were chosen for hardfacing having three different diameter range 2.4 mm, 3.2 mm and 4.0 mm. The investigation has been done on the samples (H13 die steel base/substrate material) prepared by these electrodes using three welding current 140A, 160A and 180A. Wear test, Hardness test and microstructure investigations of hardfacing layers were carried out for investigating the effect of hardfacing on mechanical properties. It was found that the welding electrodes (chromium percentage) have large affect on wear resistance property, then welding current and welding electrode diameter. Good wear resistance is observed at combination of high value chromium percentage electrode and low value welding current & 3.2 mm electrode diameter.
