Abstract

The invention relates to working of metals by pressure and can be used at production of high-duty seamless pipes of small diameters from high-alloy steels and alloys for chemical and power machine building, space engineering, medicine. A method includes producing a hollow tube billet with use casting, its mechanical working and subsequent multiple-pass cold rolling.
