Die metallischen Oxyde, die sich nach dem Zerstäuben auf der Oberfläche der Pulverteilchen in Form einer Zunderschicht befinden, sind nach dem Verpressen in dem fertigen Stahlkörper äusserst fein verteilt und bewirken die wesentliche Erhöhung der Warmfestigkeit bei hohen Temperaturen. Die Untersuchungen ergaben, dass die Festigkeit der auf diese Art hergestellten Stahlrohre bei Raumtempera-

 be delt. The metallic oxides, which are located on the surface of the powder particles in the form of a layer of scale after the atomization, are extremely finely distributed in the finished steel body after pressing and bring about a significant increase in the heat resistance at high temperatures. The investigations showed that the strength of the steel pipes manufactured in this way at room temperature
