1. Corrosion Behavior of Austenitic Stainless Steels in CO2-Saturated Synthetic Oil Field Formation Water
The corrosion behavior of austenitic and superaustenitic stainless steels was investigated in carbon dioxide-saturated synthetic oil field formation water using cyclic polarization tests. In order to measure the effect of carbon dioxide pressure, the samples were also exposed in a pressurized medium containing carbon dioxide and synthetic air. For this purpo

2. Mechanical, structural and tribological properties of superaustenitic stainless steel submitted at solution heat treatment
O aço inoxidável superasutenítico apresenta diversas aplicações tecnológicas, principalmente em ambientes corrosivos. A precipitação de diferentes fases pode alterar algumas de suas propriedades mecânicas. Tais alterações afetam vários fatores, incluindo a vida útil do material diante de condições de trabalho adversas. Neste estudo, medidas de

3. AvaliaÃÃo e ComparaÃÃo da ResistÃncia à CorrosÃo por Pites do AÃo SuperaustenÃtico AL 6XN PLUS TM e dos AÃos InoxidÃveis AustenÃticos da SÃrie AISI 304L, 316L e 317L / Evaluation and comparison of resistance to pitting corrosion of the steel superaustenitic AL 6XN PLUS â and the series austenitic stainless steels AISI 304L, 316L and 317L.
As torres de destilaÃÃo de petrÃleo sofrem corriqueiramente com problemas relacionados à corrosÃo devido ao elevado Ãndice de acidez presente no petrÃleo exigindo uma elevada resistÃncia à corrosÃo por parte dos equipamentos utilizados. Dentre os materiais empregados na fabricaÃÃo e revestimento dos equipamentos, destacam-se os aÃos inoxidÃveis

6. CORROSION OF ADVANCED STAINLESS STEEL IN PHYSIOLOGICAL SOLUTIONS / Corrosão de aços inoxidáveis avançados em meios fisiológicos
The main objective of this study was to determine the corrosion behavior of advanced stainless steels (SS) in physiological solutions to evaluate their potential for use as biomaterials. Four stainless steels were tested: a superferritic stainless steel (DIN W. Nr. 1.4575), Incoloy MA 956, containing aluminum and yttrium oxide, an austenitic stainless steel
