Abstract: This invention relates to a nitrogen-alloyed steel with a high wear resistance, which is manufactured via spray compacting and has the following composition (in mass-%): C: 0.8-2.5%, N: 0.03-0.75%, Si: 0.15-1.8%, Mn: ≦1.0%, P: ≦0.03%, S: ≦0.05%, Cr: 4.0-11.5%, Mo: 0.5-6.0%, V: ≦4.0%, Nb: ≦4.0%, W: ≦3.5%, O2: ≦0.005%, other ally constituents as needed, residual iron and usual contaminants as the residue. The chemical composition has been optimized to have the carbide-carbonitride-forming elements satisfy a wear factor Sv, and to maintain the silicon-nitrogen ratio VSiN in order to minimize the residual austenite contents. In addition, the invention relates to a procedure for manufacturing this type of steel and a composite manufactured using steel according to the invention. The steel material according to the invention has an improved wear resistance and dimensional stability.
