Abstract

The microstructure, phase composition, and mechanical properties of austenitic stainless heat-resistant chromium-nickel steel grade 08Cr18Ni10Ti (Fe–0.08%C–18%Cr–10%Ni–0.6%Ti) have been studied. The ultrafine-grained (UFG) structure in steel is formed by the Rotary Swaging (RS) method. UFG steel 08Cr18Ni10Ti has a high strength (ultimate tensile strength σB = 1580 MPa) and low ductility (elongation to failure δ ∼ 4%). Electrochemical tests of UFG steel for intergranular corrosion (IGC) resistance according to GOST 9.914–91 were carried out. The formation of a UFG structure in austenitic steel 08Cr18Ni10Ti by the RS method leads to a decrease in its IGC resistance. Annealing leads to a non-monotonic change in the mechanical properties and corrosion resistance of UFG steel. After annealing at 450–500°C, an increase in microhardness and tensile strength is observed, as well as a decrease in the ductility and IGC resistance of UFG steel. An increase in the annealing temperature to 800oC leads to a decrease in strength and an increase in the IGC resistance of UFG steel.
