The Diffusion-Hardening Effect on the Technological Properties of High-Temperature Steel

The results of research pipes diffusion hardening as an effective method for increasing the durability and reliability of power equipment are presented. The experience of commercial operation of pipes manufactured from diffusion chromized and heat-hardened steel 14 MoV6-3; on the heating surfaces of the supercritical pressure boilers are generalized. The possibility and effectiveness of this method on the example of capacities of Trypil’ska CHP are shown.
