Application and failure evaluation of ferritic stainless steels for automotive exhaust systems

摘要

Abstract:In recent years,with attention paid to global environmental problems,there have been requirements for continuous improvement of automobile fuel economy and exhaust gas purification rate.The properties of the ferritic stainless steels(FSS) used to make automobile parts have been improved.This paper introduces the construction of automotive exhaust systems and describes their main failure behaviors and corrosion evaluation procedures.
