Pressure reduction is one of the methods to get profiles of different cross-sections from starting round billets. This process has advantages over other processes of forming - fewer transitions and smaller dimensions of the bending and rolling mill.

Options of pressure reduction of starting metal-coated (steel or aluminium), paint-coated (hard) and polymer-coated (soft) steel tubes were considered in this paper.

 The following materials were used as initial:

- Steel substrate.

- Aluminum coating.

- Paint coating.

- Polymer coating.

LS-DYNA was used to carry out both 3-D and 2-D analysis of the process of coated billet deformation. 2-D analysis allowed using a smaller mesh and studying the stress-strain behavior in the contact zone thoroughly.
