CPM S30V is a martensitic (hardened) powder-made (sintered) wear and corrosion resistant stainless steel developed by Dick Barber of Crucible Industries in collaboration with knifemaker Chris Reeve. Its chemistry promotes the formation and even distribution of vanadium carbides, which are harder and more effective at cutting than chromium carbides. These vanadium carbides give the steel a very refined grain, further improving the sharpness and toughness. Despite some difficulties with a consistent heat-treat, knifemakers use CPM S30V because its composition makes it easier to grind than other powder steels although the carbides still wear down the grinder belts considerably. Its composition is as follows: Carbon 1.45%, Chromium 14.00%, Vanadium 4.00%, Molybdenum 2.00%. Barber received feed

  • La marque S30V (nom complet CPM S30V) désigne un acier inoxydable propriétaire de Crucible Materials (États-Unis). Il s'agit d'un acier martensique au chrome avec addition de vanadium.Cet acier ce caractérise par un fort volume de carbures de vanadium qui contribuent à la résistance à l'abrasion. Cet acier est produit par métallurgie des poudres ce qui lui confère une meilleure homogénéité et isotropie. La notation CPM S30V est propre à Crucible Materials. * CPM indique "Crucible Particle Metal" * S indique le caractère inoxydable. * V indique l'addition de Vanadium. Composition chimique: * C: 1.45% * Cr: 14.00% * V: 4.00% * Mo: 2.00% Dureté type: HRC58-61 (fr)
  • S30V ist ein pulvermetallurgischer Messerstahl. Der Stahl wurde vom amerikanischen Unternehmen Crucible Industries entwickelt. Es handelt sich um einen rostfreien Stahl, der neben 1,45 % Kohlenstoff und 14 % Chrom auch Zugaben von 4 % Vanadium und 2 % Molybdän enthält. Damit soll eine gute Kombination von Zähigkeit, Schnitthaltigkeit und Korrosionsbeständigkeit erreicht werden. Die Variante S35VN enthält auch Niob. (de)
  • S30V (właściwie CPM® S30V) – gatunek stali nierdzewnej opracowany przez Dicka Barbera z Crucible Materials Corporation (obecnie Crucible Industries Corporation) i produkowanej przez tę firmę w USA specjalnie do wyrobu wysokogatunkowych ostrzy i noży. Jest to nierdzewna stal proszkowa spiekana z mieszanki węglików metali oraz metali. Typowa twardość po zahartowaniu to około 58–60 HRC. Stal ta jest twardsza i bardziej odporna na korozję od stali 154CM, także produkowanej przez Crucible Industries Corporation i często wypiera ją w zastosowaniu do produkcji głowni noży wysokiej klasy. Jest typową stalą "flagowego" noża firmy Spyderco - Spyderco Military. Także Benchmade coraz częściej w nożach swoich wyższych klas zastępuje 154CM stalą S30V. (pl)

Its composition is as follows: Carbon 1.45%, Chromium 14.00%, Vanadium 4.00%, Molybdenum 2.00%. Barber received feedback from a number of other knife users and knifemakers such as Sal Glesser, Ernest Emerson, Tony Marfione, Phil Wilson, William Harsey Jr., Tom Mayo, Jerry Hossom, and Paul Bos in the development of CPM S30V. CPM S30V is considered a premium grade knife steel. It is so expensive that it strongly affects the price of the knife, and is largely used in higher-end production and custom knives. Buck Knives calls it "the absolute best blade steel available". Joe Talmadge claims it might be the ultimate high-end all-around stainless steel, due to high performance coupled with easier machinability and sharpenability than the other steels in this class.
