Duplex stainless steel 2205 has proven to be the most acceptable material for marine and saline applications because of its superior corrosion resistance with good erosion and wear resistance.. This review article focuses primarily on the morphology, mechanical properties, and corrosion resistance analysis of DSS 2205. Various microstructure characterization and corrosion testing techniques used by previous researchers are thoroughly overviewed and their results are discussed in the form of table. The effects of heat treatment and quenching time on corrosion resistance and mechanical properties of DSS 2205 are studied and critical observations are noted down. The examination of morphology carried out by previous researchers on heat treatment at several temperatures and different quenching media also comparison of with and without treated samples are studied and critical remarks have been presented. Mechanical features of DSS 2205 based on tensile test, micro-hardness test, etc. are discussed. This article includes exhaustive literature review of standard research articles which may become ready information for subsequent researchers to establish their line of action.
