Crucible Steel CPM® S45VN™ Martensitic Stainless Steel
Categories:	Metal; Ferrous Metal; Stainless Steel
Material Notes:	CPM S45VN is a martensitic stainless steel designed to offer improved corrosion and wear resistance over CPM S35VN. Its chemistry has been rebalanced so that it forms more chromium carbides, while at the same time leaving more free chromium in the matrix. The use of Niobium and Nitrogen in place of some of the Vanadium and Carbon produces an excellent combination of edge retention, wear resistance, corrosion resistance and toughness properties making this the ideal choice for an EDC knife steel. The CPM process produces very homogeneous, high quality steel characterized by superior dimensional stability, grindability and toughness compared to steels produced by conventional melting practices.
