Abstract:

       We address the impacts of carbon content on wear resistance of lowchromium alloy steel. Results show that its hardness gradually increases with the increase of carbon content. Lower wear rate and higher wear resistance are therefore acquired. Its wear rate obviously decreases and its wear resistance significantly increases with the increase of carbon content when carbon content is 0.27%~0.4%. However, wear rate tends to be stable and wear resistance hardly changes when carbon content is higher than 0.4%.

Key words: low-chromium alloy steel, carbon, wear resistance, hardness, martensite
