Abstract
A steel for the fabrication of a mechanical component by hot or cold plastic deformation has the following composition, in addition to iron and production impurities, (by wt %): (a) 0.02 at most C at most 0.15; (b) 1.3 at most Mn at most 2.0; (c) 0.04 at most Nb at most 0.10; (d) 0.10 at most Mo at most 0.35; (e) 0.001 at most B at most 0.005; (f) 0.15 at most Si at most 1.30; (g) 0.01 at most Al 0.08; (h) N at most 0.015 with Ti at least 3.5xN; (i) possibly up to 0.80 of chromium and/or up to 0.1 of sulfur. Independent claims are also included for: (a) the fabrication of a mechanical component by cold plastic deformation; (b) the fabrication of a mechanical component by hot plastic deformation; (c) a ready for use steel mechanical component.
