Abstract
Abstract Since reliability of an equipment or component is influenced through a product life cycle as a result of deficiencies occurring in design , production or due to external factors ( end - environments ) . The effect of pitting corrosion on reliability of different low alloy steels , and carbon steel alloys are estimated in this study so as to notice the failures that may result in the end environment . Results show that the reliability decreases dramatically as pit density and average pit depth increases for all the studied alloys , in a way that the alloys turn to non - useful from reliability point of view . Reliability is less effected by the corrosion rate of the relative alloy . These results are related to the fact that the pit depth and density better describe pitting corrosion rather than the corrosion rate .
