| 摘要 |
The invention relates to a component made of a steel alloy comprising iron and, as an alloying element, copper, in particular consisting (in wt% in relation to the total alloy, wherein the sum of all constituents equals 100 wt%) of iron ≥ 96, carbon 0.04 to 0.12, copper 0.5 to 2.0, manganese + silicon + chromium + nickel 0.5 to 2.5, titanium 0 to 0.1, boron 0 to 0.005, and typical unavoidable impurities. In the production of semi-finished products and of components, a combination of cold-working and annealing treatment below the recrystallization temperature is used in order to thus obtain advantageous properties with regard to strength and ductility. |
