چکیده

Low processing temperatures allow an interstitially-hardened case to be formed on the alloy with no carbide formation [1]; a “colossal” carbon supersaturation can be achieved in austenitic stainless steels such as the 316L grade [1, 2]. In addition to the notable mechanical property improvements [3, 4], such interstitially-hardened stainless steels show surprising improvements in corrosion resistance in marine environment [5].

Welding of 304L Stainless Steel with Activated Tungsten Inert Gas Process (A-TIG)

Gas tungsten arc welding is a popular process in those applications requiring a high degree of quality and accuracy. However, this process has a big disadvantage against the substantially high productivity welding procedures. Hence, many efforts have been made to improve its productivity. One of these efforts is the use of activating flux (A-TIG welding). In this study, the performance of A-TIG...

Hot Deformation Behavior of 17-7 PH Stainless Steel

To investigate the hot deformation behavior of 17-7 PH stainless steel, hot compression tests were carried out at the temperatures of 950, 1050 and 1150 oC and strain rates of 0.001 s-1 to 0.1 s-1. Accordingly, the hot working behavior was studied by the analyses of flow stress curves, work hardening rate versus stress curves, exponent- type constitutive equations and deformed microstructures. ...

Effect of Crystallographic Orientation on the Pitting Corrosion Resistance of Laser Surface Melted AISI 304L Austenitic Stainless Steel

The localized corrosion behavior of laser surface melted 304L austenitic stainless steel was studied by potentiodynamic polarization test. The extent of improvement in corrosion resistance was governed by the preferred orientation and the percentage of delta ferrite present on the surface of the laser melted sample. It was established by orientation imaging microscopy that the highest pitting p...
