Abstract:
1. A ferrous abrasion resistant sliding material having a martensite parent phase which forms a solid solution with carbon, wherein the material comprises carbon of 1.5 to 3 wt %, Cr of 7 to 25 wt % and (Mo+0.5×W) of 6 to 15 wt %, in which 0.5×W represents half of a real amount of W, with each amount being satisfied the following equation; 0.043×(Mo(wt %)+0.5×W(wt %))+2×0.085×(Cr(wt %)−5)≦carbon(wt %)≦0.038×(Mo(wt %)+0.5×W(wt %))+0.42+2×0.085×(Cr(wt %)−5), and wherein the martensite parent phase forms a solid solution with carbon of 0.2 to 0.45 wt % and comprises Cr
