doi:10.13251/j.issn.0254-6051.2023.07.031

Abstract

Abstract: Mechanical properties, microstructure and fracture morphologies of 15CrMoR steel plate under different heat treatment processes were analyzed by means of optical microscope, scanning electron microscope, tensile tester and impact tester. The results show that the mechanical properties of the steel plate tempered at 680-700 ℃ are moderate and meet the requirements, and the microstructure is composed of ferrite+pearlite+small or very small amount of bainite. After simulated post-weld heat treatment process of holding at 680 ℃ for 3-9 h, the normal temperature and 300-450 ℃ high temperature mechanical properties of the 15CrMoR steel plate can meet the standards and user requirements.

Key words: pressure vessel steel, heat treatment, tempering temperature, post-weld heat treatment, high temperature mechanical properties
