Development of High-Strength Corrosion Resistant Austenitic Steel for Oil Equipment Shafts

摘要

This article is devoted to development of high-strength corrosion-resistant austenitic steel with a nitrogen content of 0.7–1.0 wt. for use as oil equipment shafts. Steel after cold deformation has high strength and ductility properties: yield strength above 2000 MPa, relative elongation 8–9, and impact strength 65 J/cm2. Steel high strength is due to its high nitrogen content and high degree of cold deformation. The steel withstands NACE hydrogen sulfide stress cracking testing.
