Abstract (en)
[origin: WO0053913A1] The invention relates to a multi-piece piston, comprising a steel upper part and a lower part which is screwed to said upper part and which contains the hubs. The aim of the invention is to improve the strength of the lower part and its resistance to material defects and to reduce production costs. To this end, the lower part consists of a precipitation-hardened ferrite-perlite steel, preferably according to DIN EN 10267 and with added titanium and the hubs of the lower part are preferably not reinforced with bushings.
