One of ways of high-quality processing of metal billets is drawing of a lengthy wire. But at modern technology of processing total reductions during the drawing of billet into a wire are rather big (up to 99.2 %) that demands carrying out additional intermediate heat treatments. Therefore, increase in strength and plastic properties of metal without intermediate heat treatment with saving of necessary final characteristics of a wire at improvement of already existing technologies is the perspective direction of development of metal working. In this paper, the deformation of a wire made of Fe37-3FN steel by ECAP-drawing is carried out. It is shown that as a result of large deformations, the grain structure of the metal reached the UFG level, and the wire itself was highly textured, both due to a very high level of deformations, and due to the lack of intermediate annealing, the latter is dictated by energy and resource saving. It was found that after deformation by the ECAP-drawing method, the wire has an increased reserve of plasticity in comparison with the traditional drawing process, which allows its further processing with high degrees of deformation without intermediate annealing.
