Abstract: Articles are made by plastically deforming hardened steel sheet stock having relatively deep ferrite outer surface zones and a through hardened central core with an abrupt transition between the ferrite surface zones and the central core. Plastically deformed steel articles such as steel rule dies and automobile door guard beams made from such stock are described.
