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.
Abstract translation: 通过使具有较深铁素体外表面区域的硬化钢板坯和通过硬化的中心铁芯在铁素体表面区域和中心铁芯之间具有突然过渡的塑性变形来制造制品。 描述了由这种坯料制成的塑性变形的钢制品如钢制模具和汽车门保护梁。
