Abstract

High strength corrosion-resistant steel VNS65-Sh is the transitional class steel. This steel is used for manufacturing of the high-loaded power details and nodes for aviation engineering. The results of diffusion mobility hydrogen (DMH) influence on steel plasticity characteristics are shown in this article. The negative influence of surface cold working on removal of DMH during heat treatment is shown. The different modes of heat treatment providing the minimum content of DMH in samples and recovery of steel plasticity of are investigated. Positive influence of heat treatment in vacuum furnace on recovery of steel plasticity is shown.
