The corrosion behaviour of S32101 duplex and 410 martensitic stainless steel was studied through weight loss and potentiodynamic polarization in 1–6 M HCl solutions. Results show that S32101 steel has significantly lower corrosion rates than 410 steel from both tests at all concentrations with highest values of 0.04586 mm/y and 0.234 mm/y in comparison to martensitic steel with corrosion rates ...

Steel 2205 is one of the most famous duplex stainless steels. The microstructure of this steel composed of ferrite and austenite in similar amount. Therefore, in order to improve mechanical properties through microstructure, thermo mechanical processes such as controlled hot rolling and forging should be applied. It is not possible to employ the usual heat treatment. It shows the importance of ...

Duplex stainless steels (DSSS) have a microstructure composed of ferrite and austenite phases that gives them a very good combination of mechanical and corrosion properties. These steels are desirable for many applications in the chemical and petrochemical industries. In the present study, a type of stainless steel was cast, solution annealed at 1200°C for 60 min and then quenched in water. Ini...

OBJECTIVE To evaluate the quantitative effects on torque expression of varying the slot size of stainless steel orthodontic brackets and the dimension of stainless steel wire, and to analyze the limitations of the experimental methods used. MATERIALS AND METHODS In vitro studies measuring torque expression in conventional and self-ligating stainless steel brackets with a torque-measuring devi...

Experimental studies in various aspects have to be conducted to maintain stable applications of super duplex stainless steels (SDSS) because the occurrence rate of sigma phase, variable temperature and growth direction of sigma phase can influence mechanical performances of SDSS. Tensile tests of precipitated SDSS were performed under various temperatures to analyze mechanical and morphological...

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...
