Stainless Alloy 90V

Principle Design Features

CPM S90V is a unique tool steel made by the Crucible Particle Metallurgy process. It is a martensitic stainless steel to which vanadium and carbon have been added for exceptionally good wear resistance. CPM S90V offers substantial improvements in wear resistance over 440C and D2, and other high chromium steels, with corrosion resistance equal to or better than 440C. CPM S90V’s high vanadium content favors the formation of hard vanadium carbides instead of chromium carbides for wear resistance, leaving more free chromium available to provide corrosion resistance. The wear and corrosion resistance of CPM S90V make it an excellent candidate to replace 440C, where increased wear is a primary concern. It can replace D2 or other tool steels in applications where improved corrosion resistance is also of benefit.
