| Abstract | ||||
| Since stainless steel (SS) has many advantages such as excellent durability, ductility, and corrosion resistance. Duplex stainless steel (DSS) is a type of steel with superior resistance to localized and uniform corrosion. Mechanical properties of DSS with 26% chromium (Cr) were investigated under tensile, bend, impact, and hardness test. Chemical and Electrochemical corrosion tests were applied. The volume fraction of ferrite content in weld metal and heat effected zone was measured. Macro and microstructure examination were studied. DSS 26% Cr exhibited good mechanical properties and good corrosion resistance to pitting and uniform corrosion. | ||||
