20120093679METHOD FOR THE PRODUCTION OF TOOLS MADE OF ALLOYED STEEL AND TOOLS IN PARTICULAR FOR THE CHIP-REMOVING MACHINING OF METALS - The invention relates to a method for the production of tools for a chip-removing machining of metallic materials and to a tool with improved wear resistance and/or high toughness. The invention further provides an alloyed steel with a chemical composition comprising carbon, silicon, manganese, chromium, molybdenum, tungsten, vanadium, and cobalt as well as aluminum, nitrogen, and iron. The alloyed steel may be used to make tools to a hardness of greater than 66 HRC and increased chip-removing machining performance.04-19-2012
20110253270GUN BARREL OF FIREARMS - Gun barrel for firearms made from a deformed material and method for producing the gun barrel material. The material has a chemical composition in % by weight of:10-20-2011
20110253262CORROSION-RESISTANT AUSTENITIC STEEL ALLOY - An austenitic, substantially ferrite-free steel alloy and a process for producing components therefrom. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.10-20-2011
20100233500COLD-FORMING STEEL ARTICLE - A cold-forming steel article which comprises an alloy that comprises carbon, manganese, silicon, chromium, molybdenum, vanadium, tungsten and optionally, niobium in certain concentrations, as well as up to about 0.4 wt. % of accompanying elements, remainder iron and contaminants. The article is formed by atomization of a melt and hot isostatic pressing of the resultant powder. The article exhibits a hardness of at least about 60 HRC and a toughness in terms of impact strength of higher than about 50 J. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.09-16-2010
20100192476WEAR-RESISTANT MATERIAL - A wear-resistant material which comprises certain concentrations of carbon, nitrogen, oxygen, niobium/tantalum as well as other metallic elements. The material comprises a metal matrix and hard phases embedded therein. The hard phases comprise one or more of carbides, nitrides, carbonitrides, and oxide carbonitrides and have a diameter of from about 0.2 μm to about 50 μm. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.08-05-2010
20100170596CORROSION-RESISTANT AUSTENITIC STEEL ALLOY - An austenitic, substantially ferrite-free steel alloy and a process for producing components therefrom. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.07-08-2010
20100150772HOT-FORMING STEEL ALLOY - A hot-forming steel alloy comprising, in addition to iron and impurity elements, carbon, silicon, manganese, chromium, molybdenum, vanadium and nitrogen within the concentration ranges set forth in the claims. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.06-17-2010
20100147423STEEL ALLOY FOR MACHINE COMPONENTS - A machine component or part for alternating mechanical stresses up to a temperature of at most 160° C. The component or part comprises a thermally quenched and tempered steel alloy which comprises carbon, silicon, manganese, chromium, molybdenum and vanadium in certain concentrations, the remainder being iron (Fe) and accompanying elements and contaminants due to smelting. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.06-17-2010
