The applications of stainless steel are one of the most reliable solutions in concrete structures to reduce chloride-induced corrosion problems and increase the structures service life, however, due to high prices of nickel, especially in many civil engineering projects, the austenitic stainless steel is replaced by the ferritic stainless steels. Compared with austenite stainless steel, the fer...

This paper presents the results of the continued development of creep-resistant, alumina-forming austenitic (AFA) stainless steel alloys, which exhibit a unique combination of excellent oxidation resistance via protective alumina (Al2O3) scale formation and high-temperature creep strength through the formation of stable nano-scale MC carbides and intermetallic precipitates. Efforts in fiscal ye...

In metastable austenitic stainless steels, strain-induced martensitic transformation during plastic deformation enhances work hardening of the material, increasing its strength and in some cases also ductility.1,2) The presence of α’-martensite, however, may increase the susceptibility of these materials to hydrogen embrittlement phenomena, for example delayed cracking.3–6) Delayed cracking can...

The corrosion inhibition of AISI309 austenitic stainless steel by 2,2'-Bipyridyl in 0.5M H 2 SO 4 at 298K was studied using the mass loss’ method, the potentiodynamic polarization (Tafel), the linear polarization (LRP) and the electrochemical impedance spectroscopy (EIS). The results showed a mixed inhibition mode and an increase in the charge transfer resistance, due to inhibitor molecules’ ad...

The microstructure of 8 mm diameter wire produced by the severe deformation of 316L austenitic stainless steel has been examined using TEM and X-ray diffraction. The deformation imparted amounts to a true strain of 6.3. Data from previous studies on strain induced transformation of this steel have been combined with new results to show that true strains .2 are required in order to observe mecha...

one of the problems in the case of stainless steels is their low corrosion resistance against pitting corrosionin chloride containing environments, thereby leading to severe damage to industries. in this research, the pitting corrosion of 304 austenitic stainless steel was studied in 3.5% nacl solution at room temperature (25˚c) by performing electrochemical measurements (containing cyclic pola...
