Abstract:
A wear-resistant material comprising an alloy that contains: 1.5-5.5 wt. % carbon, 0.1-2.0 wt. % silicon, max. 2.0 wt. % manganese, 3.5-30.0 wt. % chromium, 0.3-10 wt. % molybdenum, 0-10 wt. % tungsten, 0.1-30 wt. % vanadium, 0-12 wt. % niobium, 0.1-12 wt. % titanium and 1.3-3.5 wt. % nickel, the remainder being comprised of iron and production-related impurities, whereby the carbon content fulfills the following condition: CAlloy[w %]=S1+S2+S3 where S1=(Nb+2(Ti+V−0.9))/a, S2=(Mo+W/2+Cr−b)/5, S3=c+(TH−900)·0.0025, where 7
