COMPONENTS MADE OF A STEEL ALLOY AND METHOD FOR PRODUCING HIGH-STRENGTH COMPONENTS

摘要

The invention concerns a component made of a steel alloy comprising iron and as alloying element copper, in particular consisting of (in wt % in relation to the total alloy, wherein the sum of all constituents equals 100 wt %) 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 goods 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.

主权项

1. Component made of a low alloyed steel comprising iron and copper, wherein the component is obtained by cold working of the steel alloy and a subsequent annealing treatment at a temperature below the recrystallization temperature of the steel alloy.
