Abstract
The invention relates to steel with high mechanical strength and wear resistance. More specifically, the invention relates to a method of reducing the segregated veins of a steel having high mechanical strength, high wear resistance and the following weight composition: 0.30%=С=1.42%; 0.05%=Si=1.5%; Mn=1.95%; Ni=2.9%; 1.1%=Cr=7.9%; 0.61%=Mo=4.4%; optionally V=1.45%, Nb=1.45%, Та =1.45% and V+Nb/2+Ta/4=1.45%; less than 0.1% borium, 0.19%(S+Se/2+Te/4), 0.01% calcium, 0.5% rare earths, 1% aluminium, 1% copper; the remainder being iron and impurities resulting from the production thereof. The composition also comprises: 800=D=1150, where D=540(C)+245(Mo+3V+1.5Nb+0.75Та)+125Cr+15.8Mn+7.4Ni+18Si. According to the invention, all or part of the molydenum is replaced by a double proportion of tungsten, such that W>0.21%, and Ті, Zr, С are adjusted so that, after said adjustment, Ті+Zr/2=0.2W, (Ті + Zr/2)XС=0.07, Ті+Zr/2=1.49% and D is unchanged at 5%. The invention also relates to the steel obtained and to a method for producing a steel part.
