Abstract
Use of an iron-based alloy for the production of sintered parts of high corrosion resistance, high wear resistance, high toughness and high compressive strength, in particular for processing plastics, having a composition, in % by weight, chromium 16.0-29.0, molybdenum 0.4-2.5, tungsten 0.3-2.0, vanadium 3.0-10.0, titanium up to 5.0, aluminium up to 1.0, boron up to 0.05, nitrogen 0.01-0.18, niobium up to 5.0, iron and preparation-related impurities as the remainder, the value formed from (% of Cr - 13) + 4.4 x (% of V - 3) + 2 x (% of Nb) + 4.2 x (% of Ti) being greater than 8.8, and the minimum carbon content of the alloy corresponding to the correlation Cmin = 0.3 + [(% of Cr - 13) x 0.06] + [(2 x % of Mo + W) x 0.03] + (% of V x 0.24) + (% of Nb x 0.13) + (% of Ti x 0.25) and the maximum carbon content of the alloy corresponds to the correlation Cmax = 0.7 + [(% of Cr - 13) x 0.06] + [(2 x % of Mo + W) x 0.03] + (% of V x 0.24) + (% of Nb x 0.13) + (% of Ti x 0.25), with the proviso that the matrix has a chromium content of at least 13% after hardening and annealing, and the carbide content is at least 25% by volume, the carbide grain size being less than 14 mu m and at least 5 % by volume of the carbides being in the form of MC carbides.
