In this study, sliding wear behavior of newly developed Fe-base Co-free hardfacing alloy (Fe–Cr–C–Si) was investigated and compared to that of Stellite 6 and Fe-base NOREM 02 in the temperatures ranging from 300 to 575 K under a contact stress of 103 MPa (15 ksi) in pressurized water. The weight loss of Fe–Cr–C–Si was equivalent to that of Stellite 6 over all temperatures range in 100-cycle wear test. The weight loss of Fe–Cr–C–Si 1000-cycle wear test increased almost linearly with increasing temperature up to 575 K. The weight loss of NOREM 02 was nearly equivalent to that of Stellite 6 below 475 K, however, galling occurred above 475 K in 100-cycle wear test. It was also found that the lubrication effect of pressurized water on the sliding wear behavior of the alloys was negligible under the present test conditions.
