Embrittlement and Corrosion Risks by majid is a document available to read on EtoBox.

1. Several cases of graphitization have occurred in reactors and piping of fluid catalytic cracking units and thermal cracking units, causing failures. Temper embrittlement and 885°F embrittlement can occur in some low alloy steels during long term exposure at high temperatures, reducing toughness. Brittle fracture can be prevented by post weld heat treatment or warm prestress hydrotesting. Creep damage rate increases with temperature and load. 2. Dissimilar metal weld cracking can occur between austenitic
