Reliability and performance evaluation of stainless and mild steel products in methanolic and aqueous media

F. H. Tobins, M. I. Williams

Abstract


Reliability and performance of stainless and mild steel products in methanolic and aqueous sodium chloride media have been investigated. Weight-loss and pre-exposure methods were used. There was a higher rate of weight-loss of mild steels and stainless steels in 1% HCl methanolic solution than in aqueous NaCl solution. Solutions containing traces of sodium nitrite were found to enhance the reliability and performance of these steels. Mercuric and stannous chlorides were observed to reduce performance and reliability. Reliability and performance of these specimens decreased with continued exposure.



Keywords: Reliability, performance, stainless steels, mild steels.
