Influence of high temperature on corrosion behavior of 304 stainless steel in chloride solutions

Abstract

Despite the excellent performance of stainless steel in diverse application, there are media of exposure may accelerate failure of several stainless steel alloys. The possibility of this failure has to be examined by measuring the effective parameters that may result in corrosion at different rates. The present study has been conducted to examine the effect of exposing specimens of 304 stainless steel to 0.5, 1.0, 1.5 and 2.0 M chloride concentration and 70, 80, and 90 °C. Electrochemical technique of measuring the potentials and currency of the examined system has been used to collect the corrosion data. Microstructure of the specimens is examined using Scanning Electron Microscopy and X- Ray Diffraction. Both of these tests revealed no serious phase change due to exposure even at severe conditions. The potentials gained show significant effect of the operation conditions.

Experimental design to study the influence of temperature, pH, and chloride concentration on the pitting and crevice corrosion of UNS S30403 stainless steel

“…Among all the influencing environmental parameters, chloride concentration, temperature, and pH play a key role in the determination of pitting and crevice corrosion performance of stainless steels [7][8][9][10][11][12][13][14][15][16][17]. It is well known that by increasing chloride concentration, temperature, and acidity of the solution, localized corrosion resistance of stainless steel generally decreases [18][19][20][21][22][23][24][25]. The role of temperature rise is mainly to control the rate of pitting initiation [1] by stabilizing of pits and hindering their re-passivation [26,27].…”

Influence of high temperature during tensile test for stainless steel using acoustic emission

“…In this study, SS304 was selected as the material for the samples. To determine the monotonic properties of the materials, three samples were meticulously prepared in adherence to the ASTM E8 Standard Test Methods for Tension Testing of Metallic Materials [8]. The tensile tests were conducted at high temperatures of 600 and 700 C respectively.…”

“…SS304 is widely used in structural applications due to its excellent corrosion resistance at high temperatures. 8 Monitoring and identifying material deformation under high-temperature conditions is paramount for ensuring safety and recognizing potential failures. Thus, the objective of this research is to monitor and investigate the effect of elevated high temperatures on the mechanical properties of stainless steel SS304.…”

“…This study aims to utilize the AE approach to examine the characteristic AE features of tensile testing at elevated high temperatures, focusing specifically on stainless steel SS304.
