Knives made of powder steel S90V

CPM S90V - martensitic stainless powder steel with the addition of vanadium and carbon for exceptionally high wear resistance. Produced by the American metallurgical company Crucible Industries LLC (USA).

High vanadium content in CPM S90V promotes the formation of solid vanadium carbides instead of chromium carbides for the highest wear resistance of the RC (especially in comparison with tool steels 440C and D2). And the presence of free chromium provides high corrosion resistance, better than that of 440C steel. The average tempering range is 60-62 HRC.

Steel composition: Carbon (C) – 2.30%, Chromium(Cr) – 14.00%, Molybdenum(We) - 1.00% , Vanadium (V) - 9.00%.

Premium steel CPM S90V it is used in the production of exclusive, author's and, less often, serial knives.
