Assessment of the Elastic Stress of 304 Stainless Steel Using Half-Cell Potential Measurement

Abstract

The aim of this paper is to investigate the effects of elastic stress for a C-ring specimen with an18.974-mm outer diameter and a 1.244-mm wall thickness. Tests are conducted on Type 304L SS material. Half-cell potential measurement specimens are used as methods of exposure and inspection The C-ring specimen for quantitatively determining the stress corrosion. Applying ASTM G38, which is a standard practice for making and using C-Ring Stress-Corrosion, was performed for elastic stress analysis. The results show that the effects of stress on the polarization curve are due to the magnitude of stress level in the specific corrosive environment.

Pengaruh Lingkungan Korosif dan Beban Mekanis Terhadap Perilaku Korosi pada Material Stainless Steel AISI-304

“…Pada beban statik internal stress terjadi selama pembebanan dibawah titik deformasi plastis, dan residual stress terjadi bila material mengalami deformasi plastis. Internal stress pada suatu bahan juga dapat timbul akibat proses perlakuan panas seperti annealing, normalizing, hardening, tempering dan proses pengelasan [7]. Pembebanan dinamik dengan beban siklik dapat mengakibatkan kegagalan pada material yang dipengaruhi oleh lingkungan walaupun beban yang diterima jauh dibawah tegangan threshold.…”
