Abstract (en)
[origin: EP0341643A1] The subject of the invention is a corrosion-resistant cold-working steel, formed by hot isostatic pressing of prealloyed powder of the composition (in percent by weight) 2.0-3.5 C, 0-1.5 Si, 0-1.5 Mn, 23.0-27.0 Cr, 0.5-2.5 Mo, 3.0-6.0 V, the remainder being Fe and unavoidable impurities, and a composite of a steel matrix and a sintered material, formed by hot isostatic pressing of a powder mixture consisting of 60 to 90% by volume of a prealloyed powder of sinterable cold-working steel matrix of the composition (in percent by weight) 2.0-3.5 C, 0-1.5 Si, 0-1.5 Mn, 23.0-27.0 Cr, 0.5-2.5 Mo, 3.0-6.0 V, the remainder being Fe and unavoidable impurities, and 40 to 10% by volume of a powder of one of the sintered materials TiC, Al2O3, B4C, VC or a mixture of two or more of these sintered materials.
