A machine component or part for alternating mechanical stresses up to a temperature of at most 160&#xb0; C. The component or part comprises a thermally quenched and tempered steel alloy which contains 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.

Steel alloy for machine components

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 &#x3bc;m to about 50 &#x3bc;m. 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.

Wear-resistant material

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: and impurities due to smelting. The material has a hardness of at least 46 to 48 HRC.

Gun barrel of firearms

A hot-working steel article, e.g., tool, comprising a material which comprises, in % by weight, 0.451 to 0.598 C, 0.11 to 0.29 Si, 0.11 to 0.39 Mn, 4.2 to 4.98 Cr, 2.81 to 3.29 Mo, 0.41 to 0.69 V, with the balance iron, contaminants and accompanying elements, as well as an alloy and a process for making said article.
