Fokin N.V., Kosmatsky Ya.I., Denysiuk S.A. Research on deformability of a new high alloy and development of a technology enabling to extrude pipes from the alloy

Abstract

The article presents the results of a study of the deformation ability of the new high alloy chromium-nickel based on defined and the possibility of its use for the production of hot pipes. The technological modes of hot extrusion of pipes of various sizes on the basis of plastometer research. A pilot industrial extrusion pipes from a new nickel-chromium alloy, analysis of which allowed us to determine the shortcomings of the technology, and corrective actions.

Keywords

Hot extrusion of pipes, pressing technology, deformation capacity, high-alloy chromium-nickel-based alloys, a pilot batch of pipes.
