Effect of Chromium Oxide Film Formation, Mainly by the INCO Method, on Hydrogen Permeability on Welded Type 304 Stainless Steel
نویسندگان
چکیده
This study assessed surface treatment techniques applicable to welded joints of stainless steel pipes and vessels for a hydrogen-permeation barrier. Specifically investigated was electrolytic polishing using electrolyte compositions consisting sulfuric acid, phosphoric methane-sulfonic acid promote uniform passive film formation on type 304 surface. also examined oxidation combination chemical oxidation, cathodic electrolysis, passivation. Hydrogen gas permeation suppression confirmed SUS304 substrates treated under selected conditions suitable thickening, homogenizing, densifying passivation films.

Effect of Weld Metal Microstructure on the Fatigue and Corrosion-Fatigue Properties of GTA-Welded 304 Stainless Steel
In this research, two different filler metals, ERNiCrMo-3 and ER309L, were used for developing different microstructure, austenite (γ) and austenite and ferrite (γ+δ) in the weld metal and fatigue properties of welded samples were evaluated in the air and sea water environments. Microstructural studies indicated a good agreement between predicted microstructures via schiffler diagram and metall...
