In this work, changes undergone at the passive layer of a new type of corrugated austenitic stainless steel (low Ni, high Mn 204Cu type) when exposed to solutions simulating that contained in the pores of concrete have been studied. Changes in the nature of the passive layer have been characterized by X-ray photoelectronic spectroscopy (XPS) and electrochemical impedance spectroscopy (EIS). Par...

The corrosion morphology in grade 2205 duplex stainless steel wire was studied to understand the nature of pitting and causes ferrite phase’s selective acidic (pH 3) NaCl solutions at 60 °C. It is shown that mechanism always pitting, which either manifests lacy cover perforation or densely arrayed cavities developing selectively on phase. Pits with a metal form concentrated chloride solutions, ...

Quality strongly depends on good mechanical properties of any manufacturing material. Similarly, quality Tungsten Inert Gas (TIG) welding Duplex Stainless Steel (DSS) like percentage elongation, ultimate tensile strength etc. Better Percentage Elongation (PE) is produced using proper parameters and their values at the time TIG welding. In this study, has been done ASTM/UNS 2205 duplex stainless...
