    • The invention relates to a hardening steel of quality class 8 and above for lifting, fastening, clamping and/or lashing means. The invention further relates to a connecting or structural element made from this steel for lifting, fastening, clamping and/or lashing technology. The invention further relates to a method for producing a connecting element or a structural element. Cost-effective production of connecting and structural elements that are resilient at low temperatures is achieved through use of the steel according to the invention, said steel having the following composition in weight percent: carbon 0.17 to 0.25, preferably 0.20 to 0.23; nickel 0.00 to 0.25, preferably 0.00 to 0.10; molybdenum 0.15 to 0.60, preferably 0.30 to 0.50; niobium 0.01 to 0.08 and/or titanium: 0.005 to 0.1 and/or vanadium: ≤ 0.16, wherein the content of niobium can preferably be between 0.01 and 0.06; aluminium 0 to 0.050, preferably 0.020 to 0.040; chromium 0.01 to 0.50, preferably 0.20 to 0.40; silicon 0.1 to 0.3, preferably 0.1 to 0.25; manganese 1.40 to 1.60; phosphorus less than 0.015; sulphur less than 0.015; copper less than 0.20 and nitrogen 0.006 to 0.014, the remainder consisting of iron and unavoidable impurities.
