  • Patent number: 4923675
    Abstract: A wear-resistant steel comprising carbon, manganese, silicon, sulpur, phosphorus, nitrogen, titanium, and iron, with the following proportions of the components, mass %:______________________________________ Carbon 0.4-1.3 Manganese 3-11.5 Sulphur up to 0.05. Phosphorus up to 0.1 Titanium 0.01-0.15 Nitrogen 0.02-0.9 Iron the balance, ______________________________________and a method of production of such steel are proposed, in which method saturation with nitrogen of an alloying additive being melted is carried out by treating said additive with a low-temperature plasma, formed from a nitrogen-containing gas at a partial pressure of nitrogen in the latter of about 0.08 to about 0.3 MPa. When mixing the melts, first a melted plain steel base is taken to about 0.7 of the melt mass and the entire mass of the nitrogen-saturated molten alloying additive is added, and then the remaining mass of the melted plain steel base is introduced.
