Niolox wurde als Schneidstahl für die Lebensmittelindustrie hergestellt und gibt einen ausgezeichneten Messerstahl ab. Around 1950-1951, David Giles of Latrobe Steel patented two “cold work” high vanadium steels [1][2] which were later named A7 and D7. Eine Gruppe US-amerikanischer Messermacher, darunter Chris Reeve, waren an Konzeption und Erprobung dieses Stahls beteiligt. D7 was a modification of D4 with higher vanadium for the same reason. 90%. Grind Full-Flat . However, it was not commonly used in knives until after the release of any of those products. The general lack of M390 in knives was presumably because Bohler was more focused on selling the steel to the plastics industry. CTS™ 204P is a powder metallurgy, chromium/vanadium stainless steel. CPM-20CV is Crucible’s version of Bohler’s popular M390 steel which also influenced Carpenter to copycat with CTS-204P. Dieser Stahl ist eine Ausnahme, denn als einziger der 10 besten Messerstähle für Taschenmesser wurde er gezielt als Messerstahl entwickelt. The Latrobe data does not state the hardness values. The vanadium does increase the hardness of the chromium carbides, however. Starting with the high carbon, 4% vanadium K190 as its basis means that M390 would have relatively high wear resistance. Gegenüber AISI 440C ist der Gehalt an Silizium und Mangan geringer, dafür wurden Vanadium und Nickel in das Legierungskonzept aufgenommen.

I have yet to sharpen that knife. Bamboo 3-layers; Bamboo 63-layers Damascus; HONKIYOTSUNA; Sekyriu Japan. To see if I was right, I enlisted the help of Shawn Houston to heat treat some M390 for me because I was unable to obtain liquid nitrogen because of COVID-19. THE CREATION. CTS-204 is a powder metallurgy, high wear, chromium/vanadium stainless steel Sheet: 0.135" thick through 0.165" thick X 22" widths X 36" lengths PD#1 view technical info PD#1 is a high toughness, high wear resistance powder metallurgy tool steel The previous specimens were heat treated at 2140°F, so we tested temperatures between 2000 and 2150°F: The chart shows that M390 is capable of rather high hardness, particularly for its level of corrosion resistance. Stainless steels with a lower carbide content like S35VN, S45VN, or Vanax also have a finer microstructure. SKU# 716104010127. CTS-XHP wird fast ausschließlich von US-amerikanischen Herstellern eingesetzt, unter anderem von Shooting Star Bill Koenig. November 22, 2014 at 7:56 pm. It is highly wear resistant so it will hold an edge for a long time. Also keine Rankingshow à la RTL. Despite the Bohler and Latrobe numbers seeming to confirm a higher result I believe the Knife Steel Nerds number is more reliable (I know, I’m biased). Sofern nicht anders angegeben, liegen die Rechte an allen Bildern und Grafiken beim Autor, sind freigegebenes Pressematerial eines Unternehmens oder sind gemeinfrei nach CC0 1.0 Universell (CC0 1.0). Stickstoff statt Kohlenstoff. Along with CTS XHP, these include CTS 204P, CTS B70P, CTS B75P, CTS BD1, CTS BD30P, CTS 204P, CTS 20CP, and CTS 40CP. When Bohler-Uddeholm is comparing with the “1st generation” they are usually referencing Crucible Steel. 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 … Große Anteile an Wolfram (13 %), Kobalt (10 %) und Vanadium (6 %) lässt die erreichbare Härte des Stahls bis auf 69 HRC steigen. This is deep metal science. Reply. Somit sind weniger Extreme in einer Richtung der Schlüssel zum Erfolg, sondern die richtige Grundidee, gelungene Feinabstimmung und natürlich allerhöchste Präzision bei der Herstellung. This double-action OTF knife also comes with a reversible pocket clip that does double-duty as a money clip and is has a double-edge on its dagger blade. Zunächst hieß er Carpenter 440XH und wurde bereits als pulvermetallurgischer Stahl produziert. [3] Kulmburg, A., and B. Hribernik. “Use of an Iron-Base Alloy in the Manufacture of Sintered Parts With a High Corrosion Resistance, a High Wear Resistance as Well as a High Toughness and Compression Strength, Especially for Use in the Processing of Synthetic Materials.” European patent 348,380, issued November 19, 1992. Die Stärke von SB-1 ist eine Kombination aus hoher Zähigkeit und ausgezeichneter Schnitthaltigkeit. I previously wrote about the performance differences (or lack thereof) between the three versions in this article. Hans Berns on the occasion of his 75th birthday.” HTM Journal of Heat Treatment and Materials 65, no. “Ferrous alloys and abrasive-resistant articles made therefrom.” U.S. Patent 2,575,218, issued November 13, 1951. You can read more about the interaction between different elements for carbide formation in this article on carbides. CPM-20CV is Crucible’s version of Bohler’s popular M390 steel which also influenced Carpenter to copycat with CTS-204P. Auch die Crucible Stähle CPM-S90V und CPM-110V liegen so knapp hinter den hier genannten Stählen, dass man keinesfalls davor zurückschrecken sollte, sich ein Taschenmesser mit einem dieser Klingenstähle zuzulegen. What if M390 is at HRC 60? You can see the rest of the Knife Steel Nerds data which includes 48 different knife steels here. CTS 204p steel composition Zuiun SPG 2 Damascus Steel; saya - dřevěné pouzdro; PRO-M Damascus VG-10; PRO-J Hammer-Eye Forged Blade; Miyabi Isshin; Sharpness Revolution 21 TAMAHAGANE Japan. CPM-S35VN hat seit seiner Markteinführung vor rund zehn Jahren weite Verbreitung erreicht. Take a look at M390 in a fixed blade, you will be suprised. Tungsten was very expensive and only available to mine in certain countries and so during war it could be difficult to obtain. Home Taschenmesser & Multitools Rike Knives Rike Thor 2-B CTS-204P Tanto Integral Taschenmesser, Titan Blue Purple Rike Thor 2-B CTS-204P Tanto Integral … And if we take into account all the cutting tests we carried out we can also say that, in terms of performance, they are also similar. Cts 204p steel Recent › Forums › Main Forum › Techniques and Sharpening Strategies › Cts 204p steel This topic has 2 replies, 3 voices, and was last updated 04/20/2019 at 8:38 am by Jeff . While 3V (low carbide) increases from 40 to 85 ft-lbs by dropping hardness from 62 to 58 Rc. I had to sharpen my Bradford 3V knife with less use. Die theoretisch erreichbare Härte beträgt 62 HRC, für die Klingen von Taschenmessern werden sie üblicherweise auf 59 oder 60 HRC gehärtet, um genügend Zähigkeit zu erhalten. Carpenter CTS-204P is a powder metallurgy stainless steel. Er eignet sich außerdem für große Küchenmesser, deren gut zwanzig Zentimeter lange Klingen bei einer Klingenstärke von nur zwei Millimetern jedem Kohlenstoffstahl mindestens ebenbürtig sind. Noch exotischer ist Carpenters Maxamet, den Knife-Blog bereits in einem Artikel ausführlich vorgestellt hat (Maxamet Klingenstahl am Beispiel des Spyderco Native 5). ATS-34 hat seinerzeit die Messerwelt verändert und RWL-34 bereichert sie bis heute. Die traurige Nachricht lautet: Die Produktion von SB-1 wurde vor kurzem eingestellt. Sehr beliebt ist der Stahl jedoch im Bereich des Timbersports, wo mit hohem Krafteinsatz Hölzer, Seile oder Bambus durchtrennt werden muss. Jahrhundert“ erklärt. SB1 ist in jeder Hinsicht erstaunlich. It was found that vanadium carbides are extremely hard and therefore contribute greatly to wear resistance with high speed steels. Obwohl er „nur“ ein schmelzmetallurgischer Stahl ist, zeigt er sich jedem Vergleich mit pulvermetallurgischen Stählen gewachsen. Die genannten und ungenannten Exoten bleiben außen vor. For the plastics industry Bohler also wanted to have a high wear resistance powder metallurgy product which had high corrosion resistance (ie stainless). The components and production process are similar. As stated by Bohler, the design target for M390 was to have high wear resistance and corrosion resistance, though they stated that high toughness is not particularly necessary for plastics processing. Einen „besten Stahl“ gibt es nicht, ausgezeichnete Messerstähle dafür einige. RWL-34 gehört zu den berühmten 14-4er Stählen, die ihren Namen durch die Legierung mit einem Prozent Kohlenstoff, 14 Prozent Chrom und vier Prozent Molybdän erhalten haben. M390 was developed by Bohler in the late 1980s as a modification to K190, which in turn was a powder metallurgy version of D7 tool steel. Latrobe separated from Timken in 2006 [9] but continued to sell Duratech 20CV and it became popular with several major knife manufacturers. Carpenter CTS-XHP Webpage Carpenter 440XH Webpage. They are effectively the same steel. Thank you Larrin! 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. Latrobe was purchased by Carpenter in 2011 [13] though Carpenter continued to sell their CTS-204P. Crucible began to sell the steel as CPM-20CV after Latrobe was purchased. Blade Thickness 0.145" (3.8 mm) Handle Olive Drab G-10 . I disagree…about M390 not being a good steel fo a fixed blade….I have a number of Bradford Knives in M390 and have no issues. Das hat einen einfachen Grund, denn technische Unterschiede gibt es zwischen Böhler M390, CPM-20V und CTS-204P nicht. In vielen Büchern findet man noch die alte Definition. Edge retention estimates based on the carbide content of M390 tend to predict a value closer to what we tested. Unterschiedliche Legierungskonzepte gibt es nicht. Einige sind haarscharf vorbei geschrammt, zum Beispiel ZDP-189, der einst als „Wunderstahl“ gehypt wurde und nach kurzer Zeit beinahe sang- und klanglos in der Versenkung verschwand. There is an email response from a Carpenter employee on the Spyderco forum [5] that provides some information on their powder metallurgy process. Carpenter began producing CTS-204P, and all three versions have been steadily building in popularity with knives ever since.
