I can think of two plates of steel, the M390 from @Bohler and CTS-204P from @Carpanter, the three of the steels have a close chemical composition, and they offer the same properties (High edge retention, high corrosion resistance, high wear resistance, toughness, and hardness), and they fall … Alle Eigenschaften von CPM-M4 liegen in der Spitzenklasse. Rivers Edge Cutlery Exclusive . I have a knife that has been used on multiple Elk and recently (0ctober 2020) 8 antelope, including separating the pelvis and rib cages with no problems at all. Crucible began to sell the steel as CPM-20CV after Latrobe was purchased. Vor drei Jahren war der Stahl noch ein Geheimtipp für Insider und genauso selten wie teuer. CTS-204P is an ultra premium steel manufactured in Philadelphia, PA. We carefully chose this steel to complete our mission of producing a 100% American made masterpiece for the majority of our knives., EDGE RETENTION. With significant amounts of Chromium, Molybdenum, Vanadium, and Tungsten, these steels are 100% ready for action. Preiswerte Taschenmesser – Budget Knives 2021, GiantMouse – Firmenportrait und das Taschenmesser Nimbus V2, Die Hawkbill Klinge – Vorteile, Nachteile und Einsatzmöglichkeiten, Impinda – Slip Joint von Chris Reeve Knives, Mehr als nur ein Küchenmesser: Chefmesser Böker Saga Damast, CDU will großflächige Waffenverbotszonen durchsetzen. American-made CTS-204P is the close equivalent to Bohler- Uddeholm M390. Keine Frage: Ein Taschenmesser mit einer Klinge aus CPM-S35VN ist niemals eine schlechte Entscheidung. In that email … Bohler promoted the improved toughness and machinability of K190 vs conventionally produced tool steels like D2 because of the powder metallurgy process which led to a refined carbide structure. Made by @Carpenter, the CTS 204P is a highly wear and corrosion-resistant stainless steel produced using Carpenter’s Powder Metallurgy process, high in vanadium, chromium, and carbon, used for high performance industrial and custom knives, food processing equipment. Granted I do not use the knife to baton wood….I have axes for that purpose. CTS 204p steel composition Bamboo 3-layers; Bamboo 63-layers Damascus; HONKIYOTSUNA; Sekyriu Japan. Bohler-Uddeholm USA also conducted CATRA and toughness experiments to help in the marketing of their knife steels at that time. https://www.patreon.com/Knifesteelnerds, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). The general lack of M390 in knives was presumably because Bohler was more focused on selling the steel to the plastics industry. In the early 1980s, Bohler steel introduced K190 steel which is a powder metallurgy version of D7 [3]. Noch exotischer ist Carpenters Maxamet, den Knife-Blog bereits in einem Artikel ausführlich vorgestellt hat (Maxamet Klingenstahl am Beispiel des Spyderco Native 5). This Sinkevich model has a 3-D rayed handle of full titanium in a stonewashed finish and the KVT ball-bearing opening system. Blade Thickness 0.145" (3.8 mm) Handle Olive Drab G-10 . Große Anteile an Wolfram (13 %), Kobalt (10 %) und Vanadium (6 %) lässt die erreichbare Härte des Stahls bis auf 69 HRC steigen. This led to reports in odd surface behavior such as low hardness readings even though the edge was fully hard. Somit sind weniger Extreme in einer Richtung der Schlüssel zum Erfolg, sondern die richtige Grundidee, gelungene Feinabstimmung und natürlich allerhöchste Präzision bei der Herstellung. They began surface grinding the material to avoid that issue. Carpenter began producing CTS-204P, and all three versions have been steadily building in popularity with knives ever since. Indem Sie diese Website nutzen, erklären Sie sich mit dieser Verwendung einverstanden. Er hatte den japanischen Stahl ATS-34 für die Messerherstellung entdeckt, der zuvor nur von Kobe Steel produziert und hauptsächlich für Kugellager eingesetzt wurde. Featuring a titanium frame lock design and a hardened steel lockbar insert, the 0456 locks open rock solid for heavy use and maximum safety. Carpenter CTS-204P is a powder metallurgy stainless steel. Latrobe separated from Timken in 2006 [9] but continued to sell Duratech 20CV and it became popular with several major knife manufacturers. Einen „besten Stahl“ gibt es nicht, ausgezeichnete Messerstähle dafür einige. The Bohler-Uddeholm tests and mine were with steels at 61-62 Rc except for 440C which was 56-59 Rc. The reduced carbon relative to K190 means that less chromium is necessary to achieve stainless levels of corrosion resistance. Elmax - It's a Medium-To-Low performance steel in my scale. Vorteile bei einer Eigenschaft muss man sich häufig mit Nachteilen bei einer anderen Eigenschaft erkaufen. Around 1950-1951, David Giles of Latrobe Steel patented two “cold work” high vanadium steels [1][2] which were later named A7 and D7. Clip Position Ambi . Er ist der einzige nicht pulvermetallurgische Stahl in der Auflistung der besten Messerstähle für Taschenmesser, kann aber mit den modernen Hightech Stählen problemlos mithalten. They began producing a copy of M390 called Duratech 20CV, and this steel started to be used by major USA knife companies. For a while I had a toughness chart which showed a relatively high value of about 8-9 ft-lbs for M390 at ~62 Rc in our toughness testing which put it close to steels like S35VN which have significantly less carbide and therefore would be expected to have superior toughness. Unterschiedliche Legierungskonzepte gibt es nicht. In the early 1900s, high carbon-high chromium steels were developed, and during World War I in England they were used as an alternative to high speed steels with high tungsten content. M390 was one of the earliest powder metallurgy stainless tool steels, coming after S60V but before SG2, Elmax, S90V, ZDP-189, or S30V. Der Zusatz Microclean steht für die nunmehr 3. Fast alle Stähle, die heute für Messerklingen verwendet werden, wurden ursprünglich nicht für Messer, sondern für Schneidaufgaben bei der industriellen Fertigung entwickelt. Der Name RWL-34 ist eine Hommage an den Messermacher Bob Loveless, dessen Initialen die Buchstabenfolge RWL ergeben (Robert Waldorf Loveless). It may be possible to somewhat increase toughness with lower hardness. Timken-Latrobe collaborated with SOG to test 20CV, reporting superior edge retention to S30V. When sharpening with diamond or CBN stones there would be no benefit. Sehr beliebt ist der Stahl jedoch im Bereich des Timbersports, wo mit hohem Krafteinsatz Hölzer, Seile oder Bambus durchtrennt werden muss. The composition is almost identical to Bohler M390. The Latrobe data shows all results relative to 440C, where 440C is set to 100, and every other result is divided by 440C to show how it does in comparison. When Bohler-Uddeholm is comparing with the “1st generation” they are usually referencing Crucible Steel. As for the manufacturing process, Carpenter's gen 2 process should produce as fine powder as Bohler-Uddeholm's Gen 3 PM does. As has been described in the history section, M390 as a steel design has been successful enough that it has been copied by at least two other companies, and has become popular in many knives. CTS-204P is an ultra premium steel manufactured in Philadelphia, PA. We carefully chose this steel to complete our mission of producing a 100% American made masterpiece for the majority of our knives., The earliest common high carbon-high chromium steel was approximately similar to D3 steel, which has higher carbon than the more common D2 which came a couple decades later, though both have about 12% Cr. Later there were other modifications of D3 such as D4 which had higher molybdenum for greater “hardenability” meaning it could be quenched more slowly and still achieve full hardness. M390 has excellent corrosion resistance, potential hardness, and edge retention. Die genannten und ungenannten Exoten bleiben außen vor. ATS-34 hat seinerzeit die Messerwelt verändert und RWL-34 bereichert sie bis heute. Dafür ist der Stahl ohne Diamanten kaum noch schleifbar und er stellt selbst die Messerhersteller vor erhebliche Probleme bei der Fertigung. Thanks for looking and good luck! https://knifesteelnerds.com/2020/01/13/s35vn-steel-properties-and-how-to-heat-treat/. Jahrhundert“ erklärt. ZDP-189 taucht hauptsächlich bei Rockstead und einigen Spyderco Modellen (Delica, Endura) im Rahmen von Sonderserien auf. Carpenter began producing CTS-204P, and all three versions have been steadily building in popularity with knives ever since. Obwohl er „nur“ ein schmelzmetallurgischer Stahl ist, zeigt er sich jedem Vergleich mit pulvermetallurgischen Stählen gewachsen. Seller assumes all responsibility for this listing. The composition is almost identical to Bohler M390. Carpenter CTS-204P is a powder metallurgy stainless steel. CTS-204P(Carpenter) - Carpenter's equivalent of Bohler-Uddeholm M390 steel and Latrobe Duratech 20CV steel.Slightly more Tungsten(W) 0.65% instead of 0.60% in other two. CPM-20V wird von Crucible Industries produziert; CTS204P wird von Carpenter Technology hergestellt. Dieser Stahl ist eine Ausnahme, denn als einziger der 10 besten Messerstähle für Taschenmesser wurde er gezielt als Messerstahl entwickelt. The differences are so small that no mere mortal will ever notice them. Last but not least: RWL-34 als Klassiker in der Liste der besten Messerstähle. Inzwischen hat sich das Bild gewandelt und M390 kommt schon bei Serienmessern der 200,- Euro Klasse häufig zum Einsatz. This good edge retention has been confirmed in many tests, including CATRA results from Bohler-Uddeholm, Latrobe, and my own. Spyderco hat eine Handvoll Modelle mit Klingen aus CPM-M4 ausgestattet (Gayle Bradley Folder, Advocate etc.). CTS-XHP bringt eine Überraschung mit. Hohe Härte geht oft mit geringer Zähigkeit einher, gute Schleifbarkeit mit geringer Schnitthaltigkeit. 60%. Derzeit reißen sich Messermacher um die verbliebenen Restposten. CTS-XHP wird fast ausschließlich von US-amerikanischen Herstellern eingesetzt, unter anderem von Shooting Star Bill Koenig. Latrobe suggested 20CV instead and SOG had better results with the manufacturability of 20CV, and contributed knives for CATRA testing by Latrobe. SOG then released the Team Leader model in Duratech 20CV. Die Gruppe hatte ihre Ziele hoch gesteckt: Der beste Messerstahl für Taschenmesser sollte entstehen. You can read more about the development of D3 and D2 in this article. Home Taschenmesser & Multitools Reate Reate K3 Mokuti Inlay, Droppoint CTS-204P Satin Finish Taschenmesser Reate K3 Mokuti Inlay, Droppoint CTS-204P Satin Finish Taschenmesser 2 … This powder metallurgy metal features vanadium-rich carbides for top use level of resistance while great chromium helps it avoid deterioration. As a Powder Metallurgy (PM) tool steel, you get a combination of impressive wear resistance and edge retention plus the added benefit of being highly corrosion resistant due to high levels of chromium. Klingen aus CPM-M4 werden auf 62 bis 65 HRC gehärtet und lassen sich am besten mit Diamantschleifsteinen nachschärfen. The toughness of the new specimens was significantly lower, and more in line with expectation based on the carbide content and relatively large carbides: So when plotting all of the steels for toughness together you can see that M390 has relatively low toughness. CTS-XHP ist trotz seiner Nähe zu AISI 440C und AISI D2 ein moderner Hochleistungsstahl, der mit sehr ordentlichen Werten in allen Disziplinen aufwarten kann. [3] Kulmburg, A., and B. Hribernik. Die traurige Nachricht lautet: Die Produktion von SB-1 wurde vor kurzem eingestellt. Vanax would also be expected to have superior corrosion resistance though M390 is likely better than Elmax. [1] Giles, David J. pulvermetallurgischen M390 Stahls. Früher sah man gut zwei Prozent Kohlenstoff als Grenze an, jenseits derer die Umformbarkeit nicht mehr gegeben war und man daher nicht mehr von Stahl, sondern von Gusseisen sprach. Stickstoff statt Kohlenstoff. M390 / CPM-20V und CTS-204P verfügen über exzellente Allround-Eigenschaften und haben faktisch keine Schwächen.
