Sustainable development of human civilization as well as responsible manufacturing require new approaches to metallurgical production chains. A major part of that requirements lies in plane of solid-state treatment of high alloyed steels and Ti-based alloys. In this work we pay an attention to the development of production of tubes of these alloys, which are widely used in energy and chemical engineering. The aim of research – an excellent microstructure, what is the warrant of the set of mechanical properties attractive for customers. The aim is reached through the creation of the deformation mode, which includes wall-thickness and diameter strain distribution, thermal balance along the treatment and auxiliary operation. That mode consists of the solutions, providing measurable considering of current chemical composition of the incoming billet. Applied approach results in fine adjustment of the solid-state treatment to the potential of chemical composition of the billet.
