Abstract

Pressed body for extrusion of objects, especially tubes, bars or similarly profiled metal objects, longitudinally drawn, dense, especially of stainless steel or high-alloy nickel steels, especially heat-resistant steels for heat exchangers, for example, stainless steels high-alloy nickel with 80 percent nickel and 20 percent chromium a capsule consisting of a thin sheet metal that preferably has a thickness of 1 to 2 mm and is advantageously low in carbon, having a carbon content of less than 0 0.015 percent, preferably less than 0.004 percent, with powder in the capsule being filled with metal powder or metal alloys or their mixtures or mixtures of metal powder or metal alloys with ceramic powders consisting preferably of spherical grains or in its predominantly spherical grain portion which is prepared in a protective gas atmosphere, preferably from an argon atmosphere to pa rtir of the desired starting material by atomization and increasing the density of the powder filled in the capsule by vibration preferably with 80 to 100 Hz approximately 60 to 71 percent of the theoretical density and after closing the capsule the density of the powder is increased by Isostatic cold pressing with a pressure of at least 4000 Bar, preferably from 4200 to 6000 Bar, especially from 4500 to 5000 Bar, subsequently or at least 80 to 93 percent of the theoretical density, characterized in that on the front face, A supplement in the form of a plate, cone, hemisphere or funnel in one or more parts of solid material and/or powder pressing is provided at the front and/or of the pressed body.
