| 20090252640 | STEEL ALLOY, A HOLDER OR A HOLDER DETAIL FOR A PLASTIC MOULDING TOOL, A TOUGH HARDENED BLANK FOR A HOLDER OR HOLDER DETAIL, A PROCESS FOR PRODUCING A STEEL ALLOY - A steel alloy is described that, in weight-%, includes 0.08-0.19 C, where 0.16≦C+N≦0.28, 0.1-1.5 Si, 0.1-2.0 Mn, 13.0-15.4 Cr, 0.01-1.8 Ni, 0.01-1.3 Mo, max. 0.7 V, max. 0.25 S, max. 0.01 Ca, max. 0.01 O, in order to improve the machinability of the steel, and balance iron and unavoidable impurities, wherein the steel alloy has a microstructure which, in a tough hardened condition, comprises a martensitic matrix with up to 30 vol-% ferrite. | 10-08-2009 |
| 20090191086 | HOT-WORKING STEEL - The present invention relates to a hot-working steel having a chemical composition, in % by weight, of 0.30-0.50% C, 0-1.5% Si, 1-1.8% Mn, 1.5-3.5% Cr, 0.3-0.9% (Mo+W/2), 0.4-0.8% (V+N/2), <3.5% (Mo+Cr), with a remainder of iron and unavoidable impurities. | 07-30-2009 |
| 20090010795 | Cold-Working Steel - The invention relates to a cold-working steel having a chemical composition, in % by weight, of 1.3-2.4 (C+N), whereof at least 0.5 C, 0.1-1.5 Si, 0.1-1.5 Mn, 4.0-5.5 Cr, 1.5-3.6 (Mo+W/2), but max 0.5 W, 4.8-6.3 (V+Nb/2), but max 2 Nb, and max 0.3 S, in which the content of (C+N) and of (V+Nb/2) are balanced in relation to each other such that the contents of these elements are within an area that is defined by the coordinates A, B, C, D, A in the system of coordinates in FIG. | 01-08-2009 |
| 20080233225 | Steel Alloy and Tools or Components Manufacture Out of the Steel Alloy - The invention relates to a powder metallurgically manufactured steel with a chemical composition containing, in % by weight: 0.01-2 C, 0.6-10 N, 0.01-3.0 Si, 0.01-10.0 Mn, 16-30 Cr, 0.01-5 Ni, 0.01-5.0 (Mo+W/2), 0.01-9 Co, max. 0.5 S and 0.5-14 (V+Nb/2), where the contents of N on the one hand and of (V+Nb/2) on the other hand are balanced in relation to each other such that the contents of these elements are within an area that is defined by the coordinates A′, B′, G, H, A′, where the coordinates of [N, (V+Nb/2)] are: A: [0.6,0.5]; B′: [1.6,0.5]; G: [9.8,14.0]; H: [2.6,14.0], and max. 7 of (Ti+Zr+Al), balance essentially only iron and impurities at normal amounts. The steel is intended to be used in the manufacturing of tools for injection moulding, compression moulding and extrusion of components of plastics, and for tools for cold working, which are exposed to corrosion. The invention also relates to construction components such as injection nozzles for engines, wear parts, pump parts, bearing components etc. Yet another field of application is the use of the steel alloy for the manufacturing of knives for food industry. | 09-25-2008 |
