Abstract
Workpiece made from a high strength steel alloy contains (in wt.%) 0.11-0.18 carbon, 0.10-0.30 silicon, 1.60-2.20 manganese, less than 0.0015 phosphorus, less than 0.010 sulfur, 1.00-2.00 chromium, less than 0.020 nitrogen, 0.020-0.060 niobium, 0.001-0.004 boron, 0.001-0.050 titanium and a balance of iron. A semi-finished product in the form of sheet metal or tube with a ductile ferritic-perlitic structure is heat treated by austenizing, cooling in air and then optionally tempered. The workpiece has a tensile strength Rm of more than 1.200 MPa at a fraction elongation A5 of more than 12 %.
