Research Progress on Mechanical Properties of High Strength Steel in Corrosive Environment

After long-term service in a complex environment, exfoliation and corrosion happen on the surface of load-bearing components of high strength steel. Under the action of alternating loads, the load-bearing components are prone to brittle failure. So the durability problem becomes increasingly prominent. The research achievements of high strength steel and their welded joints in recent years are summarized, mainly including corrosion damage mechanism, static tensile performance, hysteretic performance and fatigue performance, based on the aspects of material itself, environmental factors and load effects. Finally, the research prospect of high strength steel in corrosive environment is proposed.
