Zusammenfassung: | Process for manufacturing cylindrical hollow bodies with a circular cross-section using solid rough material of corrosion-resistant, martensitic chromium steels. A remelting block is produced and a tube blank is made therefrom, the tube blank being formed into a tube at hot forming temperature by extrusion at a deformation ratio of at least 6. Hollow bodies are cut from the resultant tube. |
