A wear pad of a band saw guide exposed to wear from a moving band saw blade is produced in a powder metallurgical manner from a steel material having the following composition, in percent by weight: 0.01-2 C, 0.01-3.0 Si, 0.01-10.0 Mn, 16-33 Cr, max. 5 Ni, 0.01-5.0 (W+Mo/2), max. 9 Co, max. 0.5 S, 1.6-9.8 N, 7.5 to 14 of (V+Nb/2), wherein the contents of N and of (V+Nb/2) are balanced in relation to each other so that the contents of the elements are within a range I″, F″, G, H, I″in a coordinate system, where the content of N is the abscissa and the content of (V+Nb/2) is the ordinate, and where the coordinates for the points (in the format [x: (N, (V+Nb/2)]) are [I″: (1.6, 7.5)], [F″: (5.8, 7.5)], [G: (9.8, 14.0)], and [H: (2.6, 14.0)], max 7 of any of Ti, Zr, and Al; and a balance essentially only iron and unavoidable impurities. |
