Abstract (en)
[origin: WO2006117030A1] The invention relates to a wear-resistant material comprising an alloy that contains: 1.5 to 5.5 wt. % of carbon; 0.1 to 2.0 wt. % of silicon; a maximum of 2.0 wt. % of manganese; 3.5 to 30.0 wt. % of chromium; 0.3 to 10 wt. % of molybdenum; 0 to 10 wt. % of tungsten; 0.1 to 30 wt. % of vanadium; 0 to 12 wt. % of niobium; 0 to 12 wt. % of titanium; 1.0 to 6.0 wt. % of nickel, the rest being composed of iron and production-related impurities. The carbon moiety meets the following condition: C<SUB>alloy</SUB> [w %] = S1 + S2 + S3, wherein S1 = (Nb + Ta + 2(Ti + V 0.9))/a, S2 = (Mo + W/2 + Cr - b)/5, S3 = c + (T<SUB>H</SUB> - 900) 0.0025, wherein 7 < a < 9, 6 < b < 8, 0.3 < c < 0.5, and 900 °C < T<SUB>H</SUB> < 1220 °C. The invention also relates to a method for producing said wear-resistant material and uses of the materials.
