Molybdenum Grades (316, 316L, 317, 317L, D319) Molybdenum in stainless steel increases the localized corrosion resistance to many chemicals. These steels are particularly effective in combatting pitting corrosion. Their most frequent use is in industrial. Stainless Grades and Properties, Stainless steel Chromium must always be present in stainless steel to provide basic corrosion resistance. Molybdenum cannot provide this basic resistance, but it significantly enhances a stainless steel's corrosion resistance, as the formula shows. The table shows that ferritic, austenitic and duplex stainless steels with different levels of pitting resistance are available, and the figure below shows that it is possible to select several different grades
This stainless steel grade is a non-magnetic metal and unable to be hardened by heat treatment. Corrosion resistance can be modified depending on the service environment. Ferritic stainless steel.
