CORROSION BEHAVIOUR OF AISI 460LI SUPER-FERRITIC STAINLESS STEEL

<p class="AMSmaintext1"><span lang="EN-GB">Following nickel and molybdenum significant price increase, nowadays the stainless steel market is moving toward an increasing use of ferritic stainless steel instead of austenitic stainless and therefore to the development of advanced ferritic stainless steels grades aimed to substitute the more expensive austenitic materials in all applications allowing it. Super-ferritic stainless steels are higher chromium (Cr) and molybdenum (Mo) steels with properties similar to those of standard ferritic alloys. Such elements increase high temperature and corrosion resistance in strong environment. This paper deal about the corrosion resistance of super-ferritic stainless steels with a Cr content ranging from 21% to 24%. </span></p>
